Question

Convert 4,700,000,000 from standard form to scientific notation. 470 × 107 47 × 108 4.7 × 109 478

Answer 1

4.7 * 10 ^9

Explanation:

4,700,000,000

Scientific notation is of the form

a * 10 ^b where a is a number between 1 and less than 10

Move the decimal so that it is a number between 1 and less than 10

4,700,000,000 becomes 4.700000000 and we moved the decimal 9 places to the left b is +9 ( positive because we moved to the left) We can drop the extraneous zeros

4.7 * 10 ^9
