Thank you for the opportunity to help you with your question! Hope your day is going well!

For the problem, it needs to be stipulated b not to be equal to 0. Because the problem would be invalid if the denominator was zero, because we cannot divide by zero.

This is a laws of exponents problem. Technically, h is raised to 1 power, and b is to the 1 power. Since it is a power raised by another power (5), we multiply.

h^(1 x 5)/ b^(1 x 5)

h^5/b^5.

Or you can use the identity,

(a/b)^n=a^n/b^n.

Either way is a good way to think about it!

Please let me know if you need any clarification. I'm always happy to answer your questions.
