is there any easy way to find exponents?

Question

5.5 x 10 to the power of 6

Answer 1

5.5 * 10^6

you just move the decimal point to the right 6 places

5500000.

 

if you're starting from a number (let's say 3712905) and you want to make it look like 5.5 * 10^6 you do it like this:

3712905.

but you want the decimal to be just to the right of the 3

you have to move the decimal over 6 places

3.712905 * 10^6
