Rewrite the rational exponent as a radical by extending the properties of integer exponents

2^(5/8)

Step-by-step explanation:

Here the base is 2, the exponent in the numerator is 7/8 and that in the denominator is 4.  Division is indicated.  The exponent rule in this case is to subtract the exponent of 2 in the denominator from the exponent of 2 in the numerator:  7/8 - 2/8 = 5/8.  Thus, the quotient in rational exponent form is

2^(5/8)
