The derivative of `log_(10x)` with respect to `x^(2)`, isA. `(1)/(2x^(2))log_(e)10`B. `(2)/(x^(2))log_(10)e`C. `(1)/(2x^(2))log_(10)^( e )`D. none of these

Answer» Correct Answer - B
Let `u=log_(10)x" and "v=x^(2)`. Then,
`(du)/(dv)=((du)/(dx))/((dv)/(dx))=((1)/(xlog_(e)10))/(2x)=(1)/(2x^(2))log_(10)e`
