(1 Pt) Find the length of the are formed by 1 y = g (23;2 + 41n(x)) fromx=3t0x=5 Preview Answers Submit Answers

Find the length of the arc: 

Please see screen shot below for question! 

So far, I've got 

y= -1/4x^2+1/2ln(x)

y'=(-x/2)+(1/(2x))

L= [sqrt(1+((-x/2)+(1/(2x)^2)] from 3 to 5

If someone could please help me solve this problem step by step that would be really helpful as I keep getting the incorrect answer. Thanks!
