How to Express numbers using powers of 10?
Any number can be expressed using the power of 10. Such a form of a number is called its
Standard form.
In this form, the number is written as a decimal number between 1.0 and 10.0 and then multiplied by a power of 10.
To convert a number to its standard form, split the number, count the number of zeros, and write it in exponential form.
For example,
(i) 5000
5000 = 5 x 1000
Number of zeros in 1000 = 3
Thus, the exponential form of 5000 = 5 × 103.
(ii) 300000000
300000000 = 3 x 100000000
Number of zeros in 100000000 = 8
Thus, the exponential form of 300000000 is 3 × 108.
(iii) 2330000000
As per the standard form, the number before the decimal point should be from 1.0 to 10.0 and 233 is 233.0,
So, 2330000000 =(2.33 × 100) × 107
= (2.33 × 102) × 107
= 2.33 × 102 × 107
= 2.33 × 109
