Q. Example to show scientific notation?

Solve the following problem.

2.45 *1014 kg + 4.00 * 1012 kg

First articulate both quantities to the same power of ten. Either quantity is able to be changed. For instance you might change 2.45 * 1014 to 245 * 1012. Then add the quantities 245* 1012 kg + 4.00 * 1012 kg * 249 *1012 kg. Write the concluding answer in scientific notation: 2.49 * 1014 kg.

Multiplying and dividing using scientific notation while multiplying or dividing quantities written in scientific notation the quantities don't have to have the same exponent. For multiplication- multiply the first factors then add the exponents and for division- divide the first factors then subtract the exponents.
