8 x 10^-3 is how many times as great as 4 x 10^-6
mamaluj [8]

For this case we can rewrite the expressions as:

3 * 10 ^ {- 3} = 0.003

That is, we run the decimal three times to the left.

4 * 10 ^ {- 6} = 0.000004

That is, we run the decimal six times to the left.

So:

0.003-0.000004 = 0.002996

So, we have that 3 * 10 ^ {- 3}is 0.002996 times bigger than 4 * 10 ^ {- 6}

Answer:

3 * 10 ^ {- 3}is 0.002996 times bigger than 4 * 10 ^ {- 6}
