The given expression is:

To find:
The single logarithm expression for the given expression.
Solution:
Quotient property of logarithm:

We have,

Using quotient property of logarithm, we get


Therefore, the required expression is
.
Answer:
Rate of change
C per meter.
Step-by-step explanation:
Given,

Then,

Change of temperature at the point say,
along the direction say,
is,
![\Big[uT_{x_2}+vT_{y_2}+wT_{z_2}\Big]_{(x,y,z)}](https://tex.z-dn.net/?f=%5CBig%5BuT_%7Bx_2%7D%2BvT_%7By_2%7D%2BwT_%7Bz_2%7D%5CBig%5D_%7B%28x%2Cy%2Cz%29%7D)

=
Hence the rate of change of temperature is
C per meter.
