Perform the following operation and express the answer in scientific notation.

Question

3.60x10^-12 + 3.60x10^-11

Answer 1

3.60X10^-12 is equal to 0.360X10^-11 (move decimal one place left)

 

Now you can add 3.60X10^-11 and 0.360X10^-11:

 

3.60X10^-11 + 0.360X10^-11 = 3.96X10^-11

 

You're really just adding 3.60 to 0.36 since the "X10^-11" is the same for both.
