If $P = \frac{A^3}{B^{5/2}}$ and $\Delta A$ is the absolute error in $A$ and $\Delta B$ is the absolute error in $B$,then the absolute error $\Delta P$ in $P$ is:

• A
  $\Delta P = \pm \left( 3 \frac{\Delta A}{A} + \frac{5}{2} \frac{\Delta B}{B} \right) P$
• B
  $\Delta P = \pm \left( 3 \frac{\Delta A}{A} + \frac{5}{2} \frac{\Delta B}{B} \right)$
• C
  $\Delta P = \pm \left( 3 \frac{\Delta A}{A} - \frac{5}{2} \frac{\Delta B}{B} \right) P$
• D
  $\Delta P = \pm \left( 3 \frac{\Delta A}{B} - \frac{5}{2} \frac{\Delta B}{A} \right) P$
