A) \[{{A}^{2}}-{{B}^{2}}{{C}^{2}}\]
B) \[\frac{A}{B}-C\]
C) \[\frac{C}{BD}-\frac{A{{D}^{2}}}{C}\]
D) \[\frac{(A-C)}{D}\]
Correct Answer: D
Solution :
| [d] (BD) \[AD=C\ell n(BD)\] |
| \[(B)\,(D)\to \] dimensionless |
| \[\left[ AD \right]=\left[ C \right]\] |
| Checking options one by one |
| \[\frac{A-C}{D}\] dimensions of A are not same as dimensions of C. Meaningless |
