$\log(A - B)$

Vedclass · Answer

(A) According to the principle of homogeneity of dimensions,physical quantities can only be added or subtracted if they have the same dimensions. Since $A$ and $B$ have unequal dimensional formulas,the operation $(A - B)$ is physically meaningless and not possible. In the expression $\log(A - B)$,the argument of the logarithm must be dimensionless,but the subtraction $(A - B)$ itself is invalid because the dimensions are unequal. Therefore,the operation $\log(A - B)$ is not possible.

$A$ and $B$ possess unequal dimensional formulas. Then,which of the following operations is not possible in any case?
