Vedclass · Answer

For $(1)$$: \mathrm{A}$ and $\frac{\mathrm{A}^{3}}{\mathrm{B}}$ may have same dimension.

For $( 2):$ As $A$ and $B$ have different dimen-

sion so $\exp \left(-\frac{\mathrm{A}}{\mathrm{B}}\right)$ is meaningless.

For $(3)$ $: \mathrm{AB}^{2}$ is meaningful.

For $4)$ $: \mathrm{AB}^{-4}$ is meaningful.

If $A$ and $B$ are two physical quantities having different dimensions then which of the following can't denote a physical quantity?
