2100 Question Fun with Radicals
What is the simplified answer for
3100 Answer Fun with Radicals
Add the coefficient of like radicals
4200 Question Fun with Radicals
What is the simplified answer for
5200 Answer Fun with Radicals
Subtract coefficient of like radicals
6300 Question Fun with Radicals
What is the simplified answer for
7300 Answer Fun with Radicals
Multiply the radicands and simplify if possible
8400 Question Fun with Radicals
What is the simplified answer for
9400 Answer Fun with Radicals
Multiply by the special 1 , then
simplify if possible
10500 Question Fun with Radicals

4
Is between and , so its square root
is between the square roots of those numbers, 2
and 3
12100 Question More Fun with Radicals
Solve
13100 Answer More Fun with Radicals
11
We are looking for the positive square root of
the perfect square, 121
14200 Question More Fun with Radicals
Estimate the
15200 Answer More Fun with Radicals
About 15.2
It falls between the perfect squares 225 and 256,
so its square root is between 15 and 16. Since
227 is closest to 225, its square root is also
closer to 15 than 16.
16300 Question More Fun with Radicals
Identify each of the radicals as rational or
irrational
17300 Answer More Fun with Radicals
Irrational, They are not perfect squares so
cannot simplify to a number that can be a fraction
Rational They are perfect squares so simplify to
the integers 7 and 10. Both 7 and 10 can be
written as fractions.
18400 Question More Fun with Radicals
Simplify
19400 Answer More Fun with Radicals
Multiply the radicands, then simplify by finding
perfect square factors.
20500 Question More Fun with Radicals
Combine
21500 Answer More Fun with Radicals
Since we have like radicands, we can subtract the
coefficients
22100 Question Exciting Exponents
Simplify
23100 Answer Exciting Exponents
The negative exponent is simplified by moving
its base to the other side of the fraction bar
and making it a positive exponent. We put a 1 in
the numerator as a place holder.
24200 Question Exciting Exponents
Evaluate
25200 Answer Exciting Exponents
1. Make the exponents happy by moving their
bases to the other side of the fraction bar.
2. Simplify by multiplying the base by itself
according to the exponent
26300 Question Exciting Exponents
Evaluate
27300 Answer Exciting Exponents
- Same base so we can Subtract the exponent.
Remember, any number to the first power is always
itself.
28400 Question Exciting Exponents
Evaluate
29400 Answer Exciting Exponents
1. Same base so we can add the exponents.
2. Now we must simplify get rid of that negative
exponent. Move the base to the other side of the
fraction bar and make the exponent positive
happy.
3. Finally, multiply the base by itself to finish
simplifying.
30500 Question Exciting Exponents
Evaluate
31500 Answer Exciting Exponents
- Simplify the negative exponent by moving its base
- to the other side of the fraction bar and make
the exponent positive. - Remember, 21 2.
2. Now, find common denominators and add the
fractions.
32100 Question Extra Exciting Exponents
What is the simplified answer for
33100 Answer Extra Exciting Exponents
Move bases with negative exponents to the other
side of the fraction bar and make the exponents
positive, happy. Bases with positive exponents
stay where they are!!
34200 Question Extra Exciting Exponents
What is the simplified answer for
35200 Answer Extra Exciting Exponents
1. The fraction reduces to
2. Move bases with negative exponents to the
other side of the fraction bar and make the
exponents positive, happy. Bases with positive
exponents stay where they are!!
3. Subtract exponents for so we have
to move that x base to the other side of the
fraction bar for our final answer.
36300 Question Extra Exciting Exponents
What is When x2 ?
37300 Answer Extra Exciting Exponents
1. Substitute 2 for the variable x and simplify
the exponent.
2. Now we have a negative exponent so we have to
move its base to the other side of the fraction
bar and make the exponent positive.
3. Multiply the base 6 by itself 3 times.
38400 Question Extra Exciting Exponents
Simplify
39400 Answer Extra Exciting Exponents
Remember, parentheses are another way of saying
multiply. 1. Bases are the same, so we can add
the exponents.
2. Since any number to the power of 1 is itself,
the answer is
40500 Question Extra Exciting Exponents
Simplify the Expressions
41500 Answer Extra Exciting Exponents
42100 Question Scientific Pot Luck
Simplify
43100 Answer Scientific Pot Luck
Step 1 simplify the fraction
Now that we simplified the fraction, we multiply
by the special 1
44200 Question Scientific Pot Luck
What is 8.6 x 10-3 in standard notation?
45200 Answer Scientific Pot Luck
Move the decimal to the left 3 spaces (exponent
tells you how far to move and which direction)
8.6 x 10-3
0.0086
46300 Question Scientific Pot Luck
What is the product of 80,000 and 90 written in
scientific notation
47300 Answer Scientific Pot Luck
Move the decimal to the left until just 1 digit
is to its left. Your exponent will be the number
of decimal hops.

48400 Question Scientific Pot Luck
Simplify the quotient and write the answer in
scientific notation
(9 x 107) (3 x 104)
49400 Answer Scientific Pot Luck
Subtract exponents 7-43
(9 x 107) (3 x 104)
Divide 9 3 3
(3 x 103)
50500 Question Scientific Pot Luck
How much greater is 9.4 x 103 than 7.5 x 10-2
51500 Answer Scientific Pot Luck
- 2 methods to solve.
- Adjust one of the numbers so the exponents are
the same. Remember LARS when moving the decimal
and changing the exponent. - Change both numbers to standard notation.
Subtract. Then, change the difference back to
scientific notation. (I find this one easier
unless the exponents are extremely big.)
- Adjust to scientific notation
