A Physical quantity P is related to four observables a,b,c and d as follows: P=(a^3b^2)/(sqrtc 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?

The accuracy in measurement depends on the limit or the resolution of the measuring instrument.A physical quantity P is related to four observables a,b,c and d as P=(a^3)(b^2)/(cd)^(1/2) . The percentage errors in measurements of a, b, c and d are 1% , 3% , 2% and 3% respectively. What is the percetage errors in the measurement of P ?
