the answer is D

anonymous · Answer

(1.1 x 10^-5) (3 x 10^-2)

So 10^x * 10^y= 10^(x+y)
just do 1.1*3 and the total of 10^-5*10^-2
This means -5+(-2)=-7

anonymous · Answer

this is because both have the same basis:10

anonymous · Answer

Wait, so that would mean that its C because -5 + -2 = -7 making it 10 ^ -7.
