Question

Find the partial elasticity...

Answer 1

Find the partial elasticity of z w.r.t. x when \[z=xye ^{x+y}\]

Answer 2

I solved this using the formula \[E _{x}= \frac{ x f'(x) }{x }\] and got the answer = 3 but the answer in the question is supposed to be Ex= 1+x. Can someone explain why that is?
