8-12.

Solve each of the following equations. Homework Help ✎

8

= 4^{x}^{(2−}^{x}^{)}200(1.05)

= 5000^{x}log

_{3}(*x*+ 5) = 420

*m*^{1.5}= 1000

Change '8' and '4' to '2' raised to a power. Then set the exponents equal to each other and solve.

Divide both sides by 200 before taking the log of both sides and bringing the '*x*' down.

Rewrite the equation in exponential form.
