X to the third power = 125/27

nika2105 [10]

When raising a fraction to a power, we can raise the numerator and denominator to the power. To find x, we need to find the cube root of both 125 and 27. That is, the numbers that when multiplied by themseelves 3 times result in 125 and 27.

$\sqrt[3]{125} = 5$

$\sqrt[3]{27} =3$

So x = $\frac{5}{3}$
