The following Topics and Sub-Topics are covered in this chapter and are available on MSVgo:
Exponents and Powers is an important NCERT maths chapter that explains the basics of exponential functions and their importance. You must have learned the concept of exponents and power in your basic algebra class, where you use powers over variables. For example, to simplify (a + b)2 = a2 + 2ab + b2.
The general form of exponents is written as (a)n, where a and n are any unique natural numbers.
The expanding of (a)n = a x a x a x a x a x a x……..n times.
For example, (2)4 = 2 x 2 x 2 x 2 = 16
The (a)n is the shorthand notation of a very large number that has been written in a simple form.
Let’s check some basic laws of exponents that apply to the exponent and power numbers.
Apart from these three basic laws, we have some exponent and power rules that come into play. We will check them below.
Numbers and exponents are the basics of mathematics and are used to depict nature’s physical quantities. There are many usages of exponents and powers in different fields and industries. Some of them are given below.
Exponents and powers are an important mathematical topic used extensively in both maths and science. You must have started learning them in the algebra section and while solving proofs in the physics section. Apart from this, they are also used in chemistry and computer science. There are some simple rules and laws associated with exponents and powers that simplify their use. The rules and laws are discussed above in detail.
