Question

What is 4x10^-7 ? In write in standard form

Answer 1

0.0000004

Explanation:

To write in standard form:

For each power of 10 bigger than 0, we add a zero at the end of the number.

For each power of 10 less than 0, we add a zero before the number(the first one before the decimal point).

In this question:

4x10^(-7)

7 zeros before the number 4, with the first before the decimal point. So

0.0000004
