Answer 2

Answer:

The number of pairs of integers (n,m) which satisfy the equation

mn=4(n+m ) is​ 2 (0,0) and (8,8).

Step-by-step explanation:

mn =4(n+m )

• If n=0, then m is also 0

so,one pair being 0 and 0, 4(0+0) = 0 ; 0*0 = 0.

• if n=8 and m=8 then nm=64 and 4(n+m ) = 4×16 = 64

• Another obvious pair that satisfies the equation is 8 and 8.
