    Answer: The first number is 2000 times greater than second number.

    Step-by-step explanation:

    Let the first number be ‘x’ and second number be ‘y’

    We are given:

    x = 8\times 10^{-3}

    y = 4\times 10^{-6}

    To calculate the times, number ‘x’ is greater than number ‘y’, we divide the two numbers:

    \frac{x}{y}=\frac{8\times 10^{-3}}{4\times 10^{-6}}\\\\\frac{x}{y}=2\times 10^3\\\\x=2000y

    Hence, the first number is 2000 times greater than second number.

    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}
