Best ResponseYou've already chosen the best response.2y=5sqrt(x^3) = 5(x^(3/2)) dy/dx = 5(3/2)(x^(3/2 1)) = 15/2 (x^1/2)

Best ResponseYou've already chosen the best response.2y=x^n dy/dx = nx^(n1) this is the property I use

Best ResponseYou've already chosen the best response.0What's happening at dy/dx = 5(3/2)(x^(3/2 1)) ?

Best ResponseYou've already chosen the best response.2y=ax^n dy/dx =a( nx^(n1)) put a=1 and n=3/2

Best ResponseYou've already chosen the best response.0Uhm, sorry to ask, but could you type dy/dx = 5(3/2)(x^(3/2 1)) in Latex (The Equation Editor)? I don't think I'm understanding it correctly.

Best ResponseYou've already chosen the best response.0That was just showing you an of how to work the power rule. I rewrote the sqrt as x^1/2
