Exponents are an expression to show how many times to multiply a number by itself.
An exponent (also known as ‘power’) shows us how many times a number (called the ‘base’) is to be multiplied by itself. If we are given , 2 is the base, and 3 is the exponent. This simply means that 2 is to be multiplied by itself 3 times. To evaluate this exponent - we can write it out like this: .
Note: Any number to the power of 1, is the number itself. (so )
Note: Any number to the power of 0 = 1. (so )
