\\\\( P = \\dfrac{a^3 b^2}{\\sqrt{c} d} \\\\)Maximum fractional error in P is given by\\\\(\\dfrac{\\Delta P}{P} = \\pm \\left[3\\dfrac{\\Delta a}{a} + 2\\dfrac{\\Delta b}{b}+ \\dfrac{1}{2}\\dfrac{\\Delta c}{c}+ \\dfrac{\\Delta d}{d}\\right]\\\\)On putting above value: \\\\(= \\pm \\dfrac{13}{100} = 0.13 \\\\)Percentage error in \\\\(P = 13\\\\) %Value of P is given as 3.763.By rounding off the given value to the first decimal place, we get \\\\(P = 3.8\\\\).
