If $Q= \frac{X^n}{Y^m}$ and $\Delta X$ is absolute error in the measurement of $X,$ $\Delta Y$ is absolute error in the measurement of $Y,$ then absolute error $\Delta Q$ in $Q$ is 
  • A$\Delta Q =  \pm \left( {n\frac{{\Delta X}}{X} + m\frac{{\Delta Y}}{Y}} \right)$
  • B$\Delta Q =  \pm \left( {n\frac{{\Delta X}}{X} + m\frac{{\Delta Y}}{Y}} \right)Q$
  • C$\Delta Q =  \pm \left( {n\frac{{\Delta X}}{X} - m\frac{{\Delta Y}}{Y}} \right)Q$
  • D$\Delta Q =  \pm \left( {n\frac{{\Delta X}}{X} - m\frac{{\Delta Y}}{Y}} \right)$
