I need to use the first 4 non zero terms binomial Taylor series:
$(1+x)^r = \sum^{\infty}_{n=0} {(r n)x^n}$ centered at $0$
I need to use this series to approximate $(1.2)^{1/4}$ and find the error of this approximation.
I understand that $r = \frac{1}{4}$ and $x = 0.2$, but i am not sure how to proceed with that information.
What exactly is the question asking me to do? This topic is new to me so I am not sure how to start this problem.
