Simplify each radical expression. Assume all variables

Question

represent positive real numbers

�ãa^10

Answer 1

again when I post it does not read right.

it is sqrt a^10

Answer 2

One of the rule of exponents tells us that the square root of a number a raised to an exponent n is the same number raised to an exponent of n/2.
Thus the square-root of a² is a^2/2 = a¹
In the particular example given,
sqrt(a¹⁰)
= a^10/2
= a⁵
