Hi everyone,

Can you please tell me if this is correct and if it isn't can you show me what I did wrong?

Find the interval:

y^3 square root of (2y^4-1)dy

u=2y^4-1

du=8y^3dy

y^3dy=du/8

y^3square root of 2y^4-1dy=

square root of u du/8=

square root of u/8=

u^(3/2)/9+c=

1/9(2y^4-1)^(3/2)+c

Thank you very much
