Mathematicians have powers

We usually say that witches, wizards and fairies have powers. What is a Power in Maths? We have three words for the same concept: power, exponents and indices. But, what is that?

In a power, we have two main parts:

1. The exponent of a number says how many times to use the number in a multiplication (2 in the example)

2. The base, that says what number is multiplied by itself (8 in the example)

.

Try on the following website to multiply any number by itself as many times as you want using exponents: See website

Once you know everything about powers, you only have to go over the index laws.

To finish with powers, have a little practice by doing these exercises.
