Question from Pete, a student:

Hi,
How do you express √h-4 in exponential form. I am having a lot of trouble with this one.
thanks
Pete

Hi Pete. It looks like you wrote this:

cube root of h^-4

The radical sign with a 3 in the crook means cube root. That means the same as the exponent of 1/3.

(h^-4)(1/3)

Remember that with rules of exponents, you multiply the exponents together to simplify from this form:

h^(-4/3)

Hope this helps,
Stephen La Rocque.
