A small error in the measurement of the ...

A small error in the measurement of the quantity having the highest power (in a given forumla) will contribute maximum percentage error in the value of the physcial quantity to whom it is related. Explain why.

We have already established that when
`x= (I^a m^b)/(t^c), them (Deltax)/(x)xx100 = +-(a(DeltaI)/(I) + b(Deltam)/(m) + c(Deltat)/(t))xx100`
This is the percentage error in x. We find that maximum contribution to percentage error comes from the
highest power (a or b or c) in the given formula.
