Find the value of 125^(2/3)

laws of indices state that the denominator of the fraction is the root of the number or letter, and the numerator of the fraction is the power to raise the answer to. Therefore, first we handle the 3 on the bottom of the fraction and cube root the 125 giving us 5. Then we handle the 2 left over by squaring the 5 we just got giving us 25
