3-110.
1. Solve the following equations for x, if possible. Some you can solve exactly, others approximately. If a solution is not possible, explain how you know. Homework Help ✎

1. 1x = 5

2. 2x = 9

3. 25(x+1) = 125x

4. 8x = 25 · 44

11 = 1
13 = 1
12 = 1
14 = 1

No solution. Explain why.

Rewrite in exponential form.

81 and 27 can both be rewritten as powers of 3.

Simplify the exponents and solve for x.

$x=\frac{8}{3}=2.\overline{6}$
