Answer 1

Hi Jesset,

This is really similar to the question you had a few days ago. For a more detailed look at each step individually, look back at the last question I answered for you. Remember that the steps I would go through to solve the problem would be to (1) Convert all the numbers into scientific notation, (2) Multiply/divide all the numbers by each other (excluding the 10^# terms) - for this step I got ~2.2, and (3) multiply/divide the 10^# terms together. Remember that when multiplying exponents with the same bases (in this problem, all the bases are 10), you can add the exponents, and when dividing you can subtract the exponents. So for this I got 10²⁷. So in the end, I got ~2 x 10²⁷ as my answer. Hope this helps!
