Find the derivative of the following functions (it is to be understand that a,b,c,d,p,q,r and s are fixed non-zero constants and m and n are integers):
`4sqrt(x)-2`

Explanation

Let `y=4sqrt(x)-2`
`rArr(dy)/(dx)=(d)/(dx)(4sqrt(x)-2)`
`=4(d)/(dx)x^(1//2)-(d)/(dx)(2)`
`=4.(1)/(2)x^(-1//2)-0=(2)/sqrt(x)`
