express 125 as a power of 5 Hence find the value of x for wich 25x = sqrt125/5 ????????

$$\\125=5*5*5=5^3\\\\
25x=\frac{\sqrt{125}}{5}\\\\
125x=\sqrt{125}\\\\
x=\frac{\sqrt{125}}{125}\\\\
x=\frac{5\sqrt{5}}{125}\\\\
x=\frac{\sqrt{5}}{25}\\\\$$

.

Haven't heard of one like this in ages.

Think it could be 5x5x5 or 5₃
