Question

I would like to know the answer to this question so I can move on to the next question and get done with this

Answer 1

0.004

1) Since we have the following product:

$4\times10^{-3}$

To write it out into the Standard notation, let's multiply 4 by 10 to the negative third power like this:

2)

$4\times10^{-3}=4\times\frac{1}{1000}=\frac{4}{1000}=0.004$

Note that 0.004 is the Standard Notation while 4 x 10^-3 is the Scientific Notation. And to divide 4 by 1000 we need to move that dot to the left (3 decimal places) for we have a negative exponent.

3) Hence, the answer is 0.004
