A physical quantity P is related to four observably a,b,c and d as follows `P=a^(3)b^(3)//c^(1//2)` 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?
