The Attempt at a Solution
I'm not really sure what I'm doing wrong.
i integrated...[tex]5y^2/2*y^(3/2)/(3/2)+3y^(3/2)/(3/2)
then i plugged in stuff so...F(b)-F(a)...f(4)-(f1)
I got (40*8/3+16)-(5/2*2/3+2) which gave me 357/3...the correct answer is 76 and I have no idea what I'm doing wrong, I've redone this problem 5 times and doublechecked to no avail :-(
