If p = 77 and q = 11, Prove pq = qp And also write what this property is known as ? 
Given p = 77, q = 11
Now, we have to prove:
pq = qp
Put the values of p and q from above and we get:
77 X 11 = 11 X 77
847 = 847
L.H.S. = R.H.S.
Hence proved pq = qp
This property is known as Commutative Property for Multiplication of Whole Numbers.
