**MathMate**, Saturday, July 25, 2009 at 9:44amOne 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(a^{10})

= a^{10/2}

= a^{5}
