Solution

First, we need to find the gradient of the scalar field T(x,y,z) = x^2yz. The gradient of a scalar field is a vector field whose components are the first order derivatives of the scalar field.

The gradient of T(x,y,z) = x^2yz is given by:

Grad(T) = ∇T = (dT/dx, dT/dy, dT/dz)

where dT/dx, dT/dy, and dT/dz are the partial derivatives of T with respect to x, y, and z respectively.

So,

dT/dx = 2xyz dT/dy = x^2z dT/dz = x^2y

Therefore, Grad(T) = (2xyz, x^2z, x^2y)

Next, we need to find the divergence of the gradient of T, which is a scalar field. The divergence of a vector field is a scalar field whose value at a point is the limit of the average value of the dot product of the vector field and the outward unit normal vector on a small sphere centered at the point as the radius of the sphere approaches zero.

The divergence of Grad(T) is given by:

Div(Grad(T)) = ∇.(Grad(T)) = d(2xyz)/dx + d(x^2z)/dy + d(x^2y)/dz

= 2yz + x^2 - x^2 = 2yz

Finally, we need to evaluate Div(Grad(T)) at the point P(2.4, 2.5, -1.5). Substituting x = 2.4, y = 2.5, and z = -1.5 into Div(Grad(T)) = 2yz, we get:

Div(Grad(T)) at P(2.4, 2.5, -1.5) = 22.5-1.5 = -7.5

So, the divergence of the gradient of the scalar field T(x,y,z) = x^2yz at the point P(2.4, 2.5, -1.5) is -7.5.
