Question

Find derivative of the following :-


$y \: = \: 5 \sqrt{x} - \frac{3}{ {x}^{2} } - 7x + 15$
​

Answer 1

We know that y= k+ p+..... Then. y' = k' + p'.. now in yr question ;. y= 5√x -3/x^2 -7x+15. [ dy/dx = d (x^n)/dx = nx^n-1]. y'= (5/2√x )+(6/x^3) -7 is yr answer..

Answer 2

derivative with respect to x

$\frac{dy}{dx} = \frac{5}{2 \sqrt{x} } - \frac{6}{ {x}^{3} } - 7$

hope it's helpful mate!!
