Scientific notation is a special way we choose for writing numbers. So the numers
are written in scientific notation. In this way, we have a quotient of two numbers written in scientific notation. To solve this problem, we have:
![\frac{6.47}{3.36}\times 10^{[-15-(-29)]}=1.92559524\times 10^{(-15+29)} \\ \\ \therefore 1.92559524\times 10^{14} \ or \ \boxed{1.92559524e+14}](https://tex.z-dn.net/?f=%5Cfrac%7B6.47%7D%7B3.36%7D%5Ctimes%2010%5E%7B%5B-15-%28-29%29%5D%7D%3D1.92559524%5Ctimes%2010%5E%7B%28-15%2B29%29%7D%20%5C%5C%20%5C%5C%20%5Ctherefore%201.92559524%5Ctimes%2010%5E%7B14%7D%20%5C%20or%20%5C%20%5Cboxed%7B1.92559524e%2B14%7D)
The division has been performed using the rules for operation with exponentiation.
