Understanding Exponents

Introduction

Exponents are an expression to show how many times to multiply a number by itself.

Terms

Exponent - The number of times to multiply the base
Base - The number being multiplied

Lesson

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 $2^{3}$, 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: $2^{3} = 2 * 2 * 2 = 8$.

Note: Any number to the power of 1, is the number itself. (so $3^1 = 3$)

Note: Any number to the power of 0 = 1. (so $4^0=1$)
