10
Solve the equation. (Type 3)
Rewrite the equation so that the powers have the
same base.
When the equation is a power power with the
same base, make the exponents equal and solve.
11
Solve the equation. (Type 3)
12
Solve the equation. (Type 3)
13
Solve the equation. (Type 4)
If the equation is a power number, then log
both sides with the base the same as the base of
the power.
Since the power is the base for the log should be
4.
