A Physical quantity P is related to four observables a, b, c and d as follows:
P = \(\frac{a^3b^2}{\sqrt c d}\). The percentage errors of measurement in a, b,c, and d are 1 %, 3%, 4% and 2% respectively. What is the percentage error in the quantity P? If the value of P calculated using the above relation turns out to be 3.763, to what value should you round off the result?
