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.

a^m × aⁿ = a^m+n

Negative Exponent Law: A base with negative power equals the reciprocal of it with positive power.

a^-m = 1/a^m

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.

a^m ÷ aⁿ = a^m-n
