Answer 1

The answer is a. which is 4 x 10‐⁷

Answer 2

4 times 10 to the negative seventh power

Explanation:

We can see that the decimal has 6 zeros before it, and then it’s 4.

since there are 7 digits after the decimal point, we put 10 to the negative seventh power.

that gives us 0.0000001

to get 0.0000004, we need to multiply ten to the negative seventh power (0.0000001) by 4
