EXPONENTS AND RADICALS
EXPONENTS and RadicalsNotesMODULE - 1 AlgebraMathematics Secondary Course 392 EXPONENTS AND RADICALSWe have learnt about multiplication of two or more real numbers in the earlier lesson. Youcan very easily write the following4 4 4 = 64,11 11 11 11 = 14641 and2 2 2 2 2 2 2 2 = 256 Think of the situation when 13 is to be multiplied 15 times. How difficult is it to write?13 13 13 ..15 times?This difficulty can be overcome by the introduction of exponential notation. In this lesson,we shall explain the meaning of this notation, state and prove the laws of EXPONENTS andlearn to apply these.
Exponents and Radicals Notes MODULE - 1 Algebra Mathematics Secondary Course 41 From the above, we say that The notation for writing the product of a number by itself several times is called the Exponential Notation or Exponential Form. Thus, 5 × 5 × .... 20 times = 5 20 and ( 7) × ( 7) × .... 10 times = ( 7) 10 In 5 20, 5 is the base and ...
