Question

Subtract 4.3 x 10^3 - 7 x 10^2. Use pencil and paper. Describe the process of rewriting the numbers in this problem with the same power of 10.

Answer 1

To subtract 4.3 x 10^3 - 7 x 10^2, we need to rewrite the numbers with the same power of 10.

4.3 x 10^3 can be rewritten as 4300 x 10^0 or simply 4300.

Now, rewrite 7 x 10^2 as 700 x 10^0 or simply 700.

Now subtract 4300 - 700.

This gives us 3600 as the final answer.
