How many times larger is 8*10^6 than 2*10^2

The first step for solving this question is put both of your given expressions into one and then subtract them. This will look like the following:
8 ×  - 2 × 10²]
Now to make the calculation easier,, factor the expression.
(8 ×  - 2) × 10²
Evaluate the power inside the parenthesis.
(8 × 10000 - 2) × 10²
Evaluate the power outside the parenthesis.
(8 × 10000 - 2) × 100
Multiply the numbers inside the parenthesis.
(80000 - 2) × 100
Subtract the numbers in the parenthesis.
79998 × 100
Lastly,, multiply the numbers together to get your final answer.
7999800
This means that 8 ×  is 7999800 times larger than 2 × 10².
