Answer:
A and C.
Step-by-step explanation:
to get rid of the square root & n, you would have to multiply it by n on both sides of the equation, giving you r^n=a.
also to get rid of the square root & n, you can also multiply both sides of a and r by the exponential fraction with n as the denominator:
[tex]\sqrt[n]{a} =r \\(a)^\frac{1}{n} = r\\a\frac{1}{n} = r[/tex]
