         2^2x.3^y=144

        2^2x.3^y=16.9(có thể là bằng 3.48 nhưng nó không hợp lệ) 

nếu : 2^2x.3^y=16.9

         2^2x=16 thì x=2     ;3^y=9 thì y=2

 (2^2x không thể bằng 9 đk vì không có số nào 2^2x=9 đk cả)

Để n+3 chia hết cho n-2

=> n+3 chia hết cho n-2

=> n-2 +5 chia hết cho n-2

Mà n-2 chia hết cho n-2

=> 5 chia hết cho n-2 => n-2 thuộc ước của 5

=> n thuộc { 3 ; 7 }

Vậy n thuộc { 3 ; 7 } thì n+3 sẽ chia hết cho 2
