• # question_answer If $\mathbf{y=1}{{\mathbf{0}}^{\mathbf{x}}}$ is the reflection of $\mathbf{y}=\mathbf{lo}{{\mathbf{g}}_{10}}\mathbf{x}$ in the line whose equations is: A)  $\mathbf{y}=-x$                     B)  $\mathbf{y}=x$          C)  $x-2y=0$        D)  $x+2y=0$

[b] $\because y={{10}^{x}}$ And $y=lo{{g}_{10}}x$ ${{10}^{y}}=x$ Hence, option [b] is correct.
