Question: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
