6.1.7 Exponents

Definitions:

• • Base --> The number used as a factor (The number we will multiply)

  • Exponent --> Tells how many times the base is used as a factor (Tells us how many times we will multiply the base by itself)

  • Powers --> Numbers expressed using exponents

  • Perfect Squares --> Numbers likes 9, 16, and 25 are perfect squares because they are squares of whole numbers.

    • 1² = 1, which is 1 x 1 = 1

    • 2² = 4, which is 2 x 2 = 4

    • 3² = 9, which is 3 x 3 = 9

    • 4² = 16, which is 4 x 4 = 16

    • 5² = 25, which is 5 x 5 = 25

    • And so on.

  • Square Roots --> The factors multiplied to form perfect squares

    • For example, the √25 = 5, because 5 x 5  = 25

      • 5 is the factor that is used to form the perfect square 25

  • Radical Sign --> Used to indicate the finding of the square root of a number

    • √   (This is the radical sign)
