.A physical quantity P=A^(3)B^(2)/CD ,If the percentage errors in the measurement of A,B,C and Dare 1%,2%,3% and 4% then what is the maximum error in the measurement of P

A physical quantitiy X is related to four measurable quantities, a,b,c and d as give X=a^(2)b^(3)c^(5//2)d^(-2) . The percentage error in the measurement of a,b,c and d are 1%,2%,2% and 4% respectively. What is the percentage error in quantitiy X?

A physical quantity A is related to four observable a,b,c and d as follows, A=(a^2b^3)/(csqrtd) , the percentage errors of measurement is a,b,c and d,are 1% , 3% , 2% and 2% respectively. What is the percentage error in the quantity A?

A physical quantify X is related to three observations a , b, c as X = sqrt a b^(2) // c^(2) . The errors of measurement in a ,b and c are 2 % , 1 % and 3% respectively . What is the percentage error in the quantity X ?

A physical quantity Q is found ot depend on observables x, y and z obeying relation Q=(x^(3)y^(2))/(z). The percentage error in the measurments of x, y and z are 1%,2%and 4% respectively. What is percentage error in the quantity Q?

A physical quantity X is given by X=(2k^(3)l^(2))/(msqrt(n)) The percentage error in the measurement of K,l,m and n are 1%,2%, 3% and 4% respectively. The value of X is uncertain by

A physical quantity X is related to four measurable quantities a,b,c and d as follows X=a^2b^3c^((5)/(2))d^-2 . The percentage error in the measurement of a,b,c and d are 1%,2%,3% and 4% repectively. What is the percentage erroe in quantity X? If the value of X calculated on the basis of the above relation is 2.763, to what value should you round off the result.
