finding a simple solution to (-8)^(4/3)

Postby jazzyjaz » Fri Jan 14, 2011 2:02 am

Hi,

I got this to find the answer:

(-8) with a 4/3 exponent

The answer in the book says 16, but i dont understand what to do to and how to achieve 16 as a result. Can someone help me and explain how you get to 16.

Are you having trouble with the negative number, with exponents in general, or with fractional exponents specifically, such as how they relate to radicals?

When you reply, please show what you've tried so far. Thank you! :wink:

Thank you. I guess i had a problem with fractional exponents , as after reading the link you posted i found out how to further develop my problem.

Thanks again.
