Question

If one dollar bill is 0.0001 meters thick how many meters tall would a stack of 4 trillion one dollar bills be?

Answer 1

400,000,000

Explanation:

4000000000000×.0001 is the answer above

Answer 2

`4 * {10}^(8 )m \: or \: 400,000,000m`

Explanation:

Put them both into standard form.

`0.0001 = 1 * {10}^( - 4) \: and \: 4 \: trillion \: is \: 4 * {10}^(12)`

Multiply them together.

`(1 * {10}^( - 4) ) * (4 * {10}^(12)) = 4 * 10^(8)`
