3-110.

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

= 5^{x}2

= 9^{x}25

^{(}^{x}^{+1)}= 125^{x}8

= 2^{x}^{5}· 4^{4}

1^{1} = 1

1^{3} = 1

1^{2} = 1

1^{4} = 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*.
