scientific notation

what you can do is first this

7•5=35 so it would be 3.5 since in scientific notation the number being multiplied by ten and a exponent can only be a number greater than 1 less then 10 so 1<x<10

then add the exponents together for 10^-4 

so 3.5*10^-4 = 0.00035

What is (7•10^-2)(5•10^-2)???=[7 x 1/100] x [5 x 1/100]=35/10,000 =7/2,000 =0.0035.
