Simplify each radical expression. Assume all variables
represent positive real numbers
ãa^10

again when I post it does not read right.
it is sqrt a^10 
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 squareroot of a² is a^{2/2} = a¹
In the particular example given,
sqrt(a^{10})
= a^{10/2}
= a^{5}
