Calculate [tex] \sqrt{1/20} [/tex] using the extended binomial theormem. (a precision of k=4 is enough)

3. The attempt at a solution

[tex] \sqrt{1/20}= (1 + (-19/20) )^{1/2}= \sum( choose (1/2,k)*(-19/20)^k) = 1- 1/2*19/20-1/8*361/400+1/16*6589/8000 = 0.72... [/tex] is wrong.

Where is my mistake?

Thanks
