Help. Exponents

OpenStudy (stellabella146):

The sun produces 3.9 ⋅ 10^33 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 3.25 ⋅ 10^3 seconds?

OpenStudy (studygurl14):

You need to multiply the two together \(\Large (3.9\times 10^{33})\times (3.25\times 10^3)\)

OpenStudy (stellabella146):

3.9 x 3.25 = 12.675. 10^33 x 10^3 = 10^36? @StudyGurl14

OpenStudy (studygurl14):

Perfect. Now combine them to get \(\large 12.675\times 10^{36}\) But notice the 12.675 is not in scientific notation
