I was working on some new homework and I'm having a hard time antidifferentiating problems like these:

For this one, I tried multiplying it out and got

and tried to use that to find the integral, but I ran into the problem of having to differentiate

Another problem that I can't do is

for when y is greater than or equal to 1 and less than or equal to 5.

On this problem, I have to find the length of the curve. I know the process, but I can't do it if I can't antidifferentiate that equation.
