then find the value of M-
P
M-3P
M-​

Answer 1

Step-by-step explanation:

We have, m = 4pqp+q⇒m = 2p . 2qp+q⇒m2p = 2qp+q⇒m+2pm-2p = 2q+p+q2q-p-q Componendo and dividendo⇒m+2pm-2p = 3q+pq-p ......1Again, m = 4pqp+q⇒m = 2p . 2qp+q⇒m2q = 2pp+q⇒m+2qm-2q = 2p+p+q2p-p-q Componendo and dividendo⇒m+2qm-2q = 3p+qp-q .....2adding 1 and 2, we get m+2pm-2p + m+2qm-2q = 3q+pq-p + 3p+qp-q ⇒m+2pm-2p + m+2qm-2q= 3q+pq-p - 3p+qq-p ⇒m+2pm-2p + m+2qm-2q= 3q+p-3p-qq-p = 2q-pq-p = 2
