Find the arclength of the curve r(t)=(10t^2,2*sqrt(10)*t, ln t)

for 1<=t<=8

2. Relevant equations

3. The attempt at a solution

i took the derivative of each component of vector r

20t,2sqrt(10),1/t

then i square each term and square root it

int sqrt( 400t + 40 + 1/t^2)dt

i cant integrate this to find out the length tho.
