# integrate help watch

1. here we go again
integrate the following with respect to x

y=4+x4+√x

∫ (4 + x4 +
i get to there and get lost in what i'm meant to be doing

i get say
y= x8
∫x8 dx
= x9 /9 + C
2. Write as .
3. so would it go
∫ (4 + x4 +x1/2 )dx
∫ (4 + x-4 +x1/2 )dx

and then i become confused on the most of it
