00:00You have given us this question in PQR AP and we have checked the value of this question.
00:04Is
00:04First of all, we multiply it internally through PR.
00:08So this becomes PQ plus 3P square R plus 3R square P plus A cube
00:14Now we see this identity: A plus B is the whole cube.
00:18A cube plus 3A square B plus 3B square A plus B cube
00:23If that identity is established, what can we write as the whole cube of P plus A?
00:28Now there is an identity in AP P plus R is equal to 2Q
00:33We know this from the identity of the AP, if you want you can also call it verify.
00:37This becomes A, A plus D, A plus 2D, this becomes 2 times
00:422A plus 2D If we add these two then we get 2A plus 2D
00:46So that means this P plus Q, P plus R is equal to 2Q
00:51So the cube of 2Q is 2, 2 is a 4, 4, 2 is a 8 and the cube of Q is
00:56Done
00:56That means 8Q will go i.e. option number D
01:00One will just go to Ka, that is, Vagas will also be in Ka.
01:00So half of Bagas Pra Q net Сп means that the vani ko na nanga yaal means that it goes
