Writing number in index form with a prime number base?

Postby Trillian » Tue Jul 20, 2010 12:06 pm

Hi, I desperately need help in knowing how to solve a problem that requires a number to be written in index form with a prime number base. I can see the answers in the back of the text, but I have no idea how they get those answers. This is for both whole numbers and fractions.

An example of the questions are;

Write each number in index form with a prime number base
a) 8 b) 64 c) 81 d) 1/13 e) 1/49 f) 1/13^3

Your help is greatly appreciated!

Yes! Those are the answers but I don't know how they get those answers - I need to know how to work it out for myself. Thanks for replying :)
