Lesson Summary
To calculate powers of numbers, multiply the base, or a, by itself, or the exponent or power designated by b. The square root of a number x (denoted √x) is a number multiplied by itself two times in order to get x, while a cubed root is a number multiplied by itself three times.
Suppose we're contemplating buying a television with a square screen that has a side length of 18 inches, and we want to calculate the size of the screen. If a square has side length s, then we can find the area of the square using the following formula:
•A = s2
To find the area of a square, multiply the side length by itself twice. Therefore, to find the area of the television screen, substitute s = 18 into the formula and solve for the area:
•A = 182 = 18 ⋅ 18 = 324
The area of the television screen is 324 square inches. The formula that we used to find the area of the television screen, particularly s2, is an example of a power of a number.
In mathematics, a power of a number is a number raised to another number that takes on the form ab. To calculate powers of numbers, multiply the base (or a) by itself, or the exponent or power designated by b.
