RD Sharma Solutions for Class 8 Maths Chapter 2: Powers

Exponents are nothing more than the repeated multiplication of the same integers. Exponents are made up of two parts: base and power. P denotes the base, while n is the power or exponent. Exponents must be calculated according to specified criteria.

If the power of b is one, the value will stay the same as the base. If the power of any base is zero, the value becomes one. Thus, keeping the base constant and naturally the powers different will have different values.

The chapter introduces some very important concepts that are used in the calculation of very large numbers. The laws and rules of exponents are very helpful in operations with large numbers. This chapter encounters many values with negative or positive power notations, which are extremely big or extremely small. For example, in the law of exponents, any non-zero integer a, am x an = am + n, and both m and n are natural numbers.

The Maths Chapter 2 Powers explains in detail the integral exponents where we learn about different types of exponents that is from the fundamentals of adding and subtracting the numbers with the same power or same numbers with different powers, decimal number system, laws of integral exponents, to express small numbers in standard form. The comparison of very large and very small numbers, the concept of exponents, decimal number systems using exponents and powers, negative exponents and laws of exponents, powers with negative exponents, and exponents to express small numbers in normal form.
