Question 3 Part A
What is 100,000 times
100,000
using the standard method of multiplication? Write the answer as 10to a power.

100,000 * 1/100,000 would be 100,000/100,000 = 1

Using the standard method you would take any number except for 0 and multiply it by 10 to a power, that power being the number of zeros following said number or how many places the decimal point would have to be moved from 0.

Examples:

100 = 10^2

0.05 = 5*10^-2

10 = 10^1

All that said, the answer to your problem, as explained above, is 1 which is 10^0 written in the standard method
