Question

Find the partial derivative indicated. Assume the variables are restricted to a domain on which the function is defined.
f(x,y)=(x^3)(e^sqrt(3xy))
Find fx

Answer 1

On my attempt of this problem I got 3x^2e^(sqrt(3xy))+(x^3/(2sqrt(3xy))(e^sqrt(3xy)))

Answer 2

\[f_{x}=\left[ 3x ^{2}+\frac{3x ^{3}y}{2\sqrt{3xy}} \right]e ^{\sqrt{3xy}}\]

Answer 3

Did you use the product rule?

Answer 4

yes...and chain rule

Answer 5

...... so confusing

Answer 6

That's the same that I had earlier, just as Zarkon.

Answer 7

you were missing a 2

Answer 8
