  1. Exponents By:Lili

  2. 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. 56 Exponent Base

  3. 1)5x5x5x5= 54 2)2x2x2x6x6x6= 23x63 0.5x0.5x0.5=0.53 =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 Examples:

  4. Special cases: • The number with an exponent of 2 is known as the square of a number • Ex:22 • The square of a whole number is known as a perfect square • 55=25

  5. If the number with an exponent of 1 is the same as the given number Ex: 251= 25 Ex: 561= 56 More Exponents:

  6. A number with an exponent of three is known as a cube of a number Ex: 93 9x9x9= 729 The cube of a whole number is a perfect square Ex: 8, 27, 64… 2x2X2=8 3x3X3=27 4x4X4=64 Cubed Exponents:

  7. 1)2x2x2x2x2= 2)7X7X73X3= 3)98X98= 4)6X6X6= 5)3X3X4X8X4X8= 6)0.1X0.1X0.1= 7)270X270= QUIZ!

  8. 1)25 2)73x32 3)982 4)63 5)32x42x82 6)0.13 7)2702 Key!
