What are Indices, Exponents and Powers and what are the Laws of Indices
Indices, Exponents and Powers all mean the same thing. If the exponent is 3 then you will have to multiply the base 3 time by itself! So 5 to the power three is 5 x 5 x 5 = 125 (and not 15!!!!). But what is y to the power 3 times y to the power 6? And what about A to the power 5 divided by A squared? To answer these questions about Indices you need to understand the Laws of Indices. They are not difficult the learn as long as you truly understand what is going on. When you are studying for your Maths exam make sure you are comfortable working with Indices and study the following example questions well!

Congratulations! You have learned about the laws of indices and are able to work with powers now. But what do you have to do when your power or index is a fraction or a negative? What does 16 to the power 1/2 equal too and how much is 4 to the power 2? These questions and more will all be answered if you follow the link. So continue with your maths revision and learn what fractional and negative indices are!
