Exponents - Positive Powers

How does one express numbers in exponential form? This topic covers this concept and its application in some real life situations.

Topic: Numbers in Exponential Form

  • In an,

    a is called the base and n is called the exponent or power.

  • To find the value of an, multiply a by itself - n number of times.

  • The symbol '.' means multiplication.
    a . a . a = a x a x a
                = a3

  • When no exponent is given, we consider it as 1.
    a1 = a

  • When the exponent is 0, then irrespective of the base the answer is 1.
    a0 = 1

Topic: Application of Exponents

  • The expression used for calculating the number of people being contacted is written as (base) exponent

  • The base is taken as the number of people being contacted by each person.

  • The exponent will be taken as the number of rounds done.
