[ When the exponent is 2, we say “squared.” When the exponent is 3, we say “cubed.” ] We know that multiplication is a way to represent and quickly calculate repeated addition. What if we have repeated multiplication? For example, say we have . In this case, 2 is being multiplied by itself four times.
In mathematics we write this as and say “2 raised to the power 4.” The 4 is superscripted (raised) and referred to as the exponent or power. This notation tells us to take the base, 2, and multiply it by itself four times.
Let’s suppose we have . This number would be read as “5 cubed.” This is mathematical shorthand for . Thus, .
