Answer 2

Answer:

$\frac{1}{x^2 + y^2 +z^2} (2x + 2y + 2z)$ is the value of V log r

Step-by-step explanation:

r is the magnitude of a three-dimensional vector

r = $\sqrt{x^2 + y^2 + z^2}$

V is the gradient of the vector

∨ = dxdydz

V log r will be

When log function is applied on a root then the subscript half can be taken out

log $\sqrt{x^2 + y^2 + z^2}$ = $\frac{1}{2} log(x^2 + y^2 +z^2)$

V = dxdydz

$\frac{1}{x^2 + y^2 +z^2} (2x + 2y + 2z)$
