Answer:

The exponent for the answer should be -2. Therefore, the answer will be 4⁻² or 1/16.

Explanation:

When dividing fractions, you subtract the exponents as long as they have the same base.

Since the exponents both have the base of 4, subtract 9 - 11.

9 - 11 = -2

The exponent would be -2 and the answer would be 4⁻².

When an exponent is negative, you take the inverse of the base raised to the positive exponent.

Since 4² = 16 or 16/1, 4⁻² would be 1/16.

The answer would be 4⁻² or 1/16.

Hope that helps.

The mistake is that it is 1/16 not 16. The person probably did the reciprocal or incorrectly used the fraction
