3-31.

Solve each equation below for

*x*. For parts (c) and (d), use the ideas from problem 3-30 so that you do not have to use Guess and Check. Homework Help ✎2

^{(}^{x}^{+3)}= 2^{2}^{x}3

^{(2}^{x}^{+1)}= 3^{3}9

= 3^{x}^{40}8

^{70}= 2^{x}

Recall problem 3-7.

*x* = 3

See part (a).

9 = 3^{2}

See part (c), or problem 3-30 for guidance.
