Question

Write 4.257x10^-7 in standard form.

Answer 1

The answer would be C.

Answer 2

Hello!

As we are multiplying by 10^-7, we will move the decimal to the right 7 times. This means we will have 6 0's before our number after the decimal.

0.0000004257

It appears that you switched around the 4 and the 2, but we know what you were referring too.

Therefore, our answer is D.

I hope this helps!
