Find the fractional error in the measurement of ` x = A^mB^ n `

What is the fractional error?

Define fractional error.

A physical quantity rho is calculated by using the formula rho =(1)/(10)(xy^(2))/(z^(1//3)) , where x, y and z are experimentally measured quantities. If the fractional error in the measurement of x, y and z are 2%, 1% and 3% , respectively, then the maximum fractional error in the calculation of rho is

If the fractional error in the measurement of current by M.C.G. is minimum then accuracy of M.C.G. is

The fractional error ((Deltax)/x)

If x= (a)-(b) , then the maximum percentage error in the measurement of x will be
