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<sup>2/2</sup> = a¹
In the particular example given,
sqrt(a<sup>10</sup>)
= a<sup>10/2</sup>
= a<sup>5</sup>
Thus the square-root of a² is a<sup>2/2</sup> = a¹
In the particular example given,
sqrt(a<sup>10</sup>)
= a<sup>10/2</sup>
= a<sup>5</sup>
