Choices A) 13189 B) 13189.2 C) 1.32 x 10^4 D) 1.3 x 10^4 E) 1.319 x 10^4
First you have to do multiplication, keeping in mind that the number with least sig figs will determine the answer. So 3.911 has 4 sig figs, that means our answer is 3740.
When adding, we need to look at number of decimal places, one with the least will determine the answer. Since 3740. has zero decimal places, our answer should also have zero decimal places. I get 13153.
