Question

Please help, "What if you magnified the image of a cluster fly (9 millimeters) by 9*10 exponent 3? What would the length appear to be?" Please hElP

Answer 1

9000

Explanation:

This is written in scientific notation. When you have a positive exponent (x³), You move the decimal point to the right as many times as the exponent says. Since the exponent is +3, move the decimal to the right 3 spaces:

`9.0(0)\\\\90.0(1)\\\\900.0(2)\\\\9000.0(3)`

So:

`9*10^3=9000`

:Done

*Magnifying means that the image will be bigger. So, the new number has to be greater than 9. Since 9000>9, this is true.
