Question

Differentation of y=x3+2x\x-1​

Answer 1

Answer:

need to solve a list of derivatives to help me on an exam; however, I'm in doubt when they use another variable (constant) or when I have a fraction with functions that use the power rule.

For example:

y=(x+1)3x3/2.

This one I tried having u=x+1, deriving it and having v=x3/2, but I couldn't get the right answer.

And:

y=2x4b2−x2.

And this one I tried to separate the constant, like y=1b2dxdy2x4−x2, but also coudn't find the answer
