‘Exponential numbers’ is one of the fundamental subjects in mathematics. Writing the product of real numbers with positive numbers as a^n is expressed as exponential numbers. The number ‘a’ is indicated here as the base number while ‘n’ is the number of exponents. Expressing exponents as a^n means multiplying n numbers of a.
Example:
53 = 5 x 5 x 5
Rules of Exponential Numbers
∗The first power of all real numbers is itself.
So a1 = a, 51 = 5
∗For every number except zero, a^0 is equal to 1.
50 = 1
∗The power of the negative one is shown as a−1 = 1/a
5-2 = 1/52 = 1/25
∗ Power of power is calculated by multiplying the exponents.
(am)n = am.n, (53)2= 53×2= 56
