Answer 1

Step-by-step explanation: Working with scientific notation all we need to do is to move the point to the left or to the right.

Letter a. Let's Illustrate below

As we can see above, we just needed to move the point 3 times to the right which represents the

`10^(-3)`

at the end of the scientific notation.

Letter b. Let's represent it as below

As we can see above we are doing the inverse representation so we needed to move the point 7 timer to the right.
