8-80.

Solve each of the following equations for $x$.

1. $171 = 3\left(5\right)^{x}$

Divide both sides by $3$.

Since $x$ is in the exponent, you need to undo it by taking the log of both sides.

2. $171y = 3x^{5}$

You will need to use a fractional exponent or a root. Your answer will be in terms of $y$.
