Write each expression using a single exponent.

h14/h5

A. h-9

B. 1/h9

C. h19

D. h9

D. h9

To write the expression h14/h5 using a single exponent, we can subtract the exponents of h.

The exponent of h in the numerator is 14, and the exponent of h in the denominator is 5.

To subtract the exponents, we have 14 - 5, which equals 9.

Therefore, the expression h14/h5 can be written as h^9.

So, the answer is option D. h9.

To simplify the expression h^14 / h^5, you need to use the quotient rule of exponents. The rule states that when dividing two terms with the same base, you subtract the exponents.

In this case, you have h^14 divided by h^5. To simplify, subtract the exponent of h in the denominator from the exponent of h in the numerator: 14 - 5 = 9.

Therefore, the expression h^14 / h^5 can be written as h^9.

So, the correct answer is:

D. h^9
