(25a^(2)b^(8))^((1)/(2))
Expand the exponent (((1)/(2))) to the expression.
25^((1)/(2))a^(2*((1)/(2)))b^(8*((1)/(2)))
Multiply 2 by each term inside the parentheses.
25^((1)/(2))ab^(8*((1)/(2)))
Multiply 8 by each term inside the parentheses.
25^((1)/(2))ab^(4)
An expression with a fractional exponent can be written as a radical with an index equal to the denominator of the exponent.
((~(25))*ab^(4))
Pull all perfect square roots out from under the radical. In this case, remove the 5 because it is a perfect square.
((5)*ab^(4))
Multiply (5) by ab^(4) to get ab^(4)(5).
(ab^(4)(5))
Multiply ab^(4) by each term inside the parentheses.
5ab^(4)
