## RS Aggarwal Solutions Class 7 Maths Chapter 5 Exponents – Overview

In the Chapter 5 of RS Aggarwal Solutions Class 7 Maths, you will learn about the terms ‘Base’ and ‘Power’, and more concepts related to exponents.

• Meaning

The number of times a particular number is multiplied by itself represents an exponent.

Eg: A number ‘b’ is multiplied by itself 3 times. It can be written as ‘b × b × b’. In short, it can be written as b³. Here, ‘b’ is the base and ‘3’ is the power. It is studied as ‘b to the power 3’. power is always written at the top right upper corner of the base.

1. ^ is the sign of the exponent.
2. Root Radical is the inverse of the exponent function.

Eg: The inverse of 8² will be √8.

• Laws Of Exponents

Let ‘a’ and ‘b’ be real numbers.

Then,

• a³ × a² = (a)³ + (a)²

When two identical numbers are multiplied their powers get added.

• a³/a² = (a)³ – (a)²

When two identical numbers are divided their powers get subtracted.

• (a³)² = (a)³*²

When a number has two powers, both the powers get multiplied.

• a³ × b³ = (a × b)³

When two different numbers that have the same power are multiplied then both the numbers get multiplied. The power is written at the top right corner as common to the whole operation.

• a²/b² = (a/b)²

When two different numbers of the same power are divided then the numbers get divided and the power is written at the top right corner as common to the whole operation.

• a^0 = 1

For any number whose power is zero, the answer will always be equal to 1.

• a^-2 = 1/a²

If the power of a number is negative, it will become positive when we reciprocate the number.
