Use scientific notation and laws of exponents to solve. Enter your answer rounded to the number of significant digits inidcated by the given data. 

 

(1.295643 x 109)/((3.610 x 10-17)(2.511 x 106))

I did this: 

(1.295643)/((3.610)(2.511)), times 109-17+6  and I got 0.1429 x 10-2 but the answer guide says that the answer is 0.1429 x 1019. Should I be adding the exponents differently?
