RS Aggarwal Solutions Class 7 Maths Chapter 5 Ex 5.2 – Overview

Introduction

• In exponents, we multiply the same number following the number of times. Eg: we can write, 24 = 2 x 2 x 2 x 2. It means that the number ‘2’ is multiplied four times. Therefore, the term exponent refers to raising the number for a power, where we consider the exponent as the power.
• The number to which the power is raised is called a base of the power. In the example, we gave above in “24”, “2” is the base value and “4” is the exponent value.

Law Of Exponents Formulae

Considering p and q as two non-zero rational numbers, as well as, m and n as two natural numbers. Accordingly to this, the law of exponents in the following ways:
1. pm x pn = pm + n
2. (pm) n = pmn
3. pmpn = pm – n, here,  m > n
4. pmpn = 1 / pn – m, here,  n > m
5. (pq) m = pm qm

Define Power Of The Base.

The number to which the power is raised is called a base of the power. In the example, we gave above in “24”, “2” is the base value and “4” is the exponent value.

What are the important formulae in this exercise?

pm x pn = pm + n
(pm) n = pmn
pmpn = pm – n, here,  m > n
pmpn = 1 / pn – m, here,  n > m
(pq) m = pm qm, where p and q as two non-zero rational numbers, as well as, m and n as two natural numbers.
