Question

Convert each number into scientific notation

1. 4,000,000,000
2. 0.000000027
3. 67,760,000
4. 90,500
5. 540,900
6. 0.00904
7. 0.032
8. 512,000,000

Answer 1

Scientific notation is a way of writing very big numbers or very small numbers in terms of powers of 10.

The number is written in two parts:

● The digits with the decimal point after the first digit

● followed by × 10 to a power that puts the decimal point where it should be

Note that value of the number doesn't changes at all only the representation of number gets changed.

For example:- 65000000 can be written as 6.5× 10⁷ in scientific notation form.

Therefore,

4,000,000,000= 4×10⁹

0.000000027= 2.7 × 10^-8

67,760,000=6.776×10⁷

90,500=9.05×10⁴

540,900=5.409×10⁵

0.00904=9.04×10^-3

0.032=3.2×10^-2

512,000,000=5.12×10⁸
