Answer:
A: 0.453
B: 0.00000712
Step-by-step explanation:
When a there is a 10 that’s raise to the negative power, all you need to do is shift the decimal from the number to the left based on the number of the exponent. So for 453 x 10^-3, shift the decimal from 453 to the left 3 times to get 0.453. For 712 x 10^-8, shift the decimal from 712 to the left 8 times to get 0.00000712.
Hope this helped! :)
