Question 940960: Hello,
I am stuck on how to do the problem below. I think it's the exponent that is throwing me off, as I have figured out similar types of problems. Here it is:
(17.3 x 4,300)^3
(0.17 x 830)^3
This is all in one big parenthesis, with an exponent of 3, with the 0.17 x 830 as the denominator. I have to express the result in scientific notation.
Thanks :)
