જો $P = \frac{{{A^3}}}{{{B^{5/2}}}}$ અને $\Delta A$ એ $A$ ની અને $\Delta B$ એ $B$ ની નિરપેક્ષ ત્રુટિ હોય તો $P$ ની નિરપેક્ષ ત્રુટિ $\Delta P$ કેટલી થાય?
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
$\Delta P = \pm \left( { 3 \frac{{\Delta A}}{B} - \frac{5}{2}\frac{{\Delta B}}{A}} \right)P$
Solution
Here $\frac{{\Delta P}}{P} = \pm \left( {3\frac{{\Delta A}}{A} + \frac{5}{2}\frac{{\Delta B}}{B}} \right)$
