compute the expressions using scientific notation, and write your
answer in that form.
(4 x 10^-3) ( 2 x 10^-5) =
(4)(x)(10^(-3))(2)(x)(10^(-5))
(4)(x)((1)/(10^(3)))(2)(x)(10^(-5))
(4)(x)((1)/(1000))(2)(x)(10^(-5))
(4)(x)((1)/(1000))(2)(x)((1)/(10^(5)))
(4)(x)((1)/(1000))(2)(x)((1)/(100000))
(4*x)((1)/(1000))(2)(x)((1)/(100000))
(4x)((1)/(1000))(2)(x)((1)/(100000))
(4x*(1)/(1000))(2)(x)((1)/(100000))
((x)/(250))(2)(x)((1)/(100000))
((x)/(250)*2)(x)((1)/(100000))
((x)/(125))(x)((1)/(100000))
((x)/(125)*x)((1)/(100000))
((x^(2))/(125))((1)/(100000))
((x^(2))/(125)*(1)/(100000))
((x^(2))/(12500000))
(x^(2))/(12500000)
