Introduction to exponents

Introduction to exponents

Do you ever wake up wishing you had powers? Or maybe you are lucky enough to be one of the few of those out there who do! In this section, we will be learning how to write products of repeated multiplication as powers. Exponents, or powers, are a way of showing that a quantity is multiplied by itself a certain number of times. In this section, we will be learning how to identify the base and exponent of a power as well as how to write a power in expanded and standard form. When a number is written in standard form, its digits are separated into groups of three.
