Class 7 Maths Chapter 13 Exponents & Powers – Important Topics

Power: Power denotes the amount of time a number has to be multiplied by itself.

Exponent: Exponent is generally defined as a positive or negative number that represents the power to which the base number is to be raised.

Some of the rules of exponents include:

x⁰ = 1
(x^m)ⁿ = x^mn
x^m × y^m = (xy)^m
x^m ÷ y^m = (x/y)^m
x^m × xⁿ = x^m+n
x^m ÷ xⁿ = x^m-n
