Step-by-step explanation:
The first thing to simplify is the Exponent
If The Exponent is a fraction than the denominator of the fraction will be the power of the root and the numerator will be the power of the expression
It will be in the form
Where a is the denominator and b is the numerator of the fraction
The first expression 216^1/3 will be
6×6×6=216 so the expression = 6
The second expression 125^1/3 will be
5×5×5=125 so the expression =5
216^1/3 - 125^1/3
6 - 5
