Question

Convert 3,200,000 to scientific notation. HELP!

3.2 ⋅ 106

3.2 ⋅ 105

3.2 ⋅ 10−6

3.2 ⋅ 10−5

Answer 1

scientific notation simply means, leave only one digit to the left-side of the dot, and use a 10 raised at some power.

`\bf 3200000\implies 3\underline{200000.}\implies 3.200000 * 10^6\implies 3.2* 10^6`

so we moved the dot 6 slots over to the left, the 10 gets a 6 as exponent.

Answer 2

The answer is 3.2 • 10^6
