Question 329241: Laws of exponents to simplify
not sure if I will write this out correctly but I'll give it a whirl!
I also worked it and will provide my answer! Is there a way to check your answer?
question? Ohh, the # is powered^ by a fraction.
3^3/4 * 3^7/8
my solution:
3^3/4 * 3^7/8= 3 3/4*7/8= 3 36/32, but I feel that I need to simplify further? break the fraction of 36/32 down.
Am I getting the process down? I don't know why it is so confusing!
Thanks Again!

Question 329611: Hello, I am trying to figure out how to find the answer to a problem in an Appendix Application. It is to find out the weight of an object in Death Valley.
We are to use the formula , , , finally Death Valley is 282 ft below sea level.
In previous question I was to find "C" if an object weighed 100 lbs at sea level. C= 1,562,500,000 For this question,
I have figured out that sea level is 20,924,640 ft from center of earth, which makes Death Valley 20,924,358 ft.
From here my numbers are so big that they will not compute on my calculator, But if I try to covert the feet back to miles for Death Valley, I come up with the weight of 100 lbs, again. I do not think this would be right. Should I possibly be finding the perfect squares of some of these numbers and reducing them down somehow to get smaller numbers to find this wieght?
