(i) প্রত্যেকটি অনুপাত
5a-7c-13e /
5b-7d-13f
(ii) (a+c2+e) (b2+de+f2) = (ab+cd+ef)2​ please do this question's answer and then send me quickly.

Answer 1

Answer:

let a/b = c/d = e/f = k then. a = bk, c = dk and e = fk. L.H.S. = (ab + cd + ef)2. = (bk.b + dk.d + fk.f)2. = k2(b2 + d2 + f2)2.

Answer 2

(a+c2+e) (b2+de+f2)=(ab+cd+ef)2
