If +da, +db and +dx are absolute errors in a, b and x respectively, then choose the correct option(s) (a) if x = a × b, then ?x/x=±[?a/a+?b/b] (b) if x = a + b, then dx = + [da . db] (a) if x = a/b,then ?x/x=±[?a/a±?b/b] (d) if x = (a^n b^m)/c^p , then ?x/x=±[n ?a/a+m ?b/b+p ?c/c]

If +da, +db and +dx are absolute errors in a, b and x respectively, then choose the correct option(s)
    (a)    if x = a × b, then ?x/x=±[?a/a+?b/b]
    (b)    if x = a + b, then dx = + [da . db]
    (a)    if x = a/b,then ?x/x=±[?a/a±?b/b]
    (d)    if x = (a^n b^m)/c^p , then ?x/x=±[n ?a/a+m ?b/b+p ?c/c]

(a, c, d)

 

        (b) is wrong because if x = a + b then Dx = + [Da + Db]
