Answer to Question #32527 in Finance for wassim

Question

Hi,

I had a question in exam to do with partial Derivative,

The question was: Find the First partial Derivative of: P=Q^0.5 R^0.5+ Q/R with respect to Q and R..

My answer was:
d/dR= 0.5 Q^0.5 R^0.5-1+Q/R
=0.5 Q^0.5 R^ -0.5+Q/R
AND
d/dQ= 0.5Q^ -0.5 R^0.5+ Q/R
= 0.5Q^-0.5 r^0.5+Q/R

Am i Right??
