Some important Facts about Exponents and Powers worksheet for class 7

Very large numbers are difficult to read, understand, compare and operate upon. To make all these easier, we use exponents, converting many of the large numbers in a shorter form.
The following are exponential forms of some numbers? 10,000 = 104 (read as 10 raised to 4) 243 = 3 5 , 128 = 27 .
Here, 10, 3 and 2 are the bases, whereas 4, 5 and 7 are their respective exponents. We also say, 10,000 is the 4th power of 10, 243 is the 5th power of 3, etc.

EXPRESSING LARGE NUMBERS IN THE STANDARD FORM

Let us now go back to the beginning of the chapter. We said that large numbers can be conveniently expressed using exponents. We have not as yet shown this. We shall do so now.

Sun is located 300,000,000,000,000,000,000 m from the centre of our Milky Way Galaxy.
Number of stars in our Galaxy is 100,000,000,000.
Mass of the Earth is 5,976,000,000,000,000,000,000,000 kg. These numbers are not convenient to write and read. To make it convenient we use powers.
