Answer:

4^7

Explanation:

You know that an exponent signifies repeated multiplication. The value of the exponent is the number of times the base appears as a factor.

You also know that identical factors in the numerator and denominator of a fraction cancel.

The given fraction has 9 factors of 4 in the numerator, and 2 factors of 4 in the denominator. The two in the denominator cancel an equal number in the numerator, leaving a value that has 7 factors of 4:


(4^9)/(4^2)=4^(9-2)=\boxed{4^7}
