**RD Sharma Solutions for Class 8 Chapter 2 “Powers”. In this chapter, we will learn the laws of integral (positive and negative both) exponents of rational numbers. We know how to calculate the expression 5 x 5. This expression can be written more shortly, using something called exponents.**

Five⋅5=52

An expression that represents repeated multiplication of the same factor is called a power.

The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor.

Integral exponents, Here we will learn about different types of exponents (Zero exponents, Positive Exponents, Negative Exponents, etc.) right from the fundamental way of adding and subtracting the numbers with the same power or the same numbers having different powers.
