Express in Exponential Form

When the numbers given are very large like Mass of earth = 5,970,000,000,000,000,000,000 Kg. then it is not easy to read them so we write them in the form of exponents. Exponents make these numbers easy to read, write, understand and compare.

Observe 1,00,000=10X10X10X10X10=10^5

Here, "10" is called the base, and "5" is called the exponent.

10^5 is the exponential form of 1,00,000.

Examples are:

  •  2^5=2X2X2X2X2=32, Here 32 can be expressed as the product of prime factors.
  • 432=2^4X3^3 is expressed as the product of prime factors.
