I'm completely blanking on a simple exponent problem

Question

Solve for $x$:

$5x^{0.7}$ $=$ $y$

Answer 1

$$5x^{0.7}=y$$

$$x^{0.7}=\frac{y}{5}$$

$$0.7\ln x=\ln\frac{y}{5}$$

$$\ln x=\frac{\ln\frac{y}{5}}{0.7}$$

$$x=e^\frac{\ln\frac{y}{5}}{0.7}$$

$$x=\left(\frac{y}{5}\right)^\frac{1}{0.7}$$

$$x=\left(\frac{y}{5}\right)^\frac{10}{7}$$
