I M not sure this is is right this is scientific notation

(4.18x10^-4) (9x^-4)

4.18 x 9. 10^-4x10^-4 well we add the exponents

=37.62 Which gives us 10^8

37.62 is not in scientific notion so we moves the decimal to the left which gives us 3.762 we add 1 to the. The exponent which gives us 10^9

3.762 x10^9 is this right

    (4.18 * 9) = 37.62

    10^-4 * 10^-4 = 10^-8

    Then since you need to move the decimal over to make it in scientific notation, you add 1 to the 10^-8, then you get 10^-7. The problem in scientific notation is 3.726*10^-7.
