Question

Find the derivative!
f(x)=−7x^4√x+−7/(x^3√x)

Answer 1

Yay fun! I like how you put an exclamation point!

Answer 2

It looks like your problem is just a combination of the power rule and quotient rule with sum/difference rule.

Answer 3

Do you know how to do those?

Answer 4

I know the power rule well but I'm getting stuck after I change it to -28x^3(1/2sqrtx)+-7x^-3(1/2sqrtx)

Answer 5

f(x)=−7x^4√x+−7/(x^3√x)

\(f(x) = -7x^{4.5}-7x^{-3.5}\)

Answer 6

thank you!! @tkhunny
