sqrt(x)=x^(1/2)
dx=(1/2)x^(-1/2)

It's a basic application of the power rule. Turns out to be 1/(2sqrt(x))

the formula 4 solving this is n*x^n-1
sqrtx=x^1/2
on differentiation u get 1/2x^1/2-1
=1/2x^-1/2
=1/2x^1/2 (put x in dr)
=1/2sqrtx

f (x) = x^(1/2)
f `(x) = (1/2) x^(-1/2)
f `(x) = 1 / 2x^(1/2)
f `(x) = 1 / (2âx)

(1/2)x^(-1/2)
so
1/2sqrtx
