This is suppose to be 10 to the negative 2 power but I can't figure out how to type that in. The possible answers are A.0.0462B.0.462C.4.62D.462. Created by Katie Owens. science-mathematics-en - mathematics-en

You see the minus signs on energy elements.They mean you are reversing the fraction.I mean whether it is 2,it turns into half of or if it is 10 like this question that suggests 1/10 Now,right here,there may be 10^-2,that you could write this as 1/100 10 turns into one hundred considering of its vigour(-2) and 10^-1 exactly way 1/10 so overview this: (1/a hundred)+(1/10)=? As a way to sum these fractional numbers,we need to get same denominators. So i can write 1/10 as 10/100 (they are same) here it is:1/one hundred+10/a hundred=eleven/a hundred Hope helps you
