Question

\[((1/y^2)-(3/y^4)) * (y +5y^3)\]

differentiate

Answer 1

Some \(\LaTeX\) tips:
\times=\(\times\)
\frac{a}{b}=\(\frac{a}{b}\)
y^{-2}=\(y^{-2}\). The braces are used to group things together.

Okay, so do you have to differentiate this with respect to y?
\[
(y^{-2}-3y^{-4})(y+5y^3)
\]
I think negative indices are easier to work with when doing calculus.

Answer 2

yes i do have to differentiate with respect to y. i understand what you but now do i have to do the product rule?

Answer 3

I wouldn't do product rule. I would expand those bracket and differentiate term by term.

Answer 4

ohh ok i understand now thank you very much that makes everything much simpler

Answer 5

You are welcome.
