Good evening, need a little help please.......I need to find the derivative of f(x)=2x^-3-3x^-2. Thanks

Answer 1

this is a power rule:
-6x^(-4) + 6x^(-3)

Answer 2

use the all mighty power rule.
\[f(x)=2x^2-3x^{-2}\]
\[f'(x)=4x+6x^{-3}\]

Answer 3

oops typo sorry. i read
\[x^3\] when it should have been \[x^{-3}\]

Answer 4

TBates is right and i am wrong!
