3. Exponential notation is useful in situations where the same number is multiplied repeatedly. The number being multiplied is the base and the and the exponent tells you how many times the base is multiplied. 5656

4. 1)5x5x5x5= 5 4 2)2x2x2x6x6x6= 2 3 x6 3 0.5x0.5x0.5=0.5 3 =0.125 How they would be written? 1)five to the fourth power 2)two to the second power times six to the third power

5. Special cases: The number with an exponent of 2 is known as the square of a number Ex:2 2 The square of a whole number is known as a perfect square 5 5 =25

6. More Exponents: If the number with an exponent of 1 is the same as the given number Ex: 25 1 = 25 Ex: 56 1 = 56

7. Cubed Exponents: A number with an exponent of three is known as a cube of a number Ex: 9393 9x9x9= 729 The cube of a whole number is a perfect square Ex: 8, 27, 64… 2x2X2=8 3x3X3=27 4x4X4=64
