Question 866102: Hello, so I have been stuck on this question for about two days and I just can't figure out how to go about solving it:
Find the first three terms in the expansion:
(x+1/x)^30
Thank you for your help!
Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! plug in 1 for x (1+1/1)^30
plug in 2 for x (2+1/2)^30
plug in 3 for x (3+1/3)^30
a=(1+1/1)^30,
b=(2+1/2)^30,
c= (3+1/3)^30
a = 1073741824,
b = 931322574615478515625/1073741824,
c = 1000000000000000000000000000000/205891132094649
a=1.0737×10^9, b=8.6736×10^11, c=4.8569×10^15
