• A physical parameter a can be determined by measuring the parameters b, c, d and e using the relation a = ${b^\alpha }{c^\beta }/{d^\gamma }{e^\delta }$. If the maximum errors in the measurement of b, c, d and e are ${b_1}$%, ${c_1}$%, ${d_1}$% and ${e_1}$%, then the maximum error in the value of a determined by the experiment is
