NCERT Solutions for Class 8 Mathematics
Exponents: An exponent is a number that represents the number of times a factor is multiplied by itself. If number 9 is multiplied n number of times, then it will be represented as:
9×9×9×............n= 9n
Thus Exponential formula is an = a × a × a × .........… × a
Multiplication Law: According to the multiplication law, the product of two exponents having the same base but different powers is equal to the base raised to the sum of two powers.
am × an = am+n
Negative Exponent Law: A base with negative power equals the reciprocal of it with positive power.
a-m = 1/am
Division Law: According to this law, when two exponents with the same bases but different powers are divided, it results in the base being raised to the difference between two powers.
am ÷ an = am-n
