Oh! where does the square root sign end?Distribute.
Is it:√y (1+y)dy
y^1/2 (1+y) dyy^1/2 (1+y) dy
=y^1/2 (dy) +2y^1/2 (dy)
Is this correct?.........................No
No. Take it slowly:y^1/2 (1+y) dy
=y^1/2 (dy) +2y^1/2 (dy)
Is this correct?
You are in calculus and do not know that only y1/2*2 gives you 2y1/2. So y1/2*y can't be 2y1/2y^1/2 (1+y) dy
=y^1/2 (dy) +2y^1/2 (dy)
Is this correct?
