Question:৯ সরল কর `(2^(n + 4) - 4.2^(n + 1))/2^(n + 2) -: 2`

Answer সমাধান: `(2^(n + 4) - 4.2^(n + 1))/(2^(n + 2) -: 2)` 

          `= (2^n xx 2^4 - 4 xx 2^n xx 2^1)/(2^(n + 2) -: 2^1)`

          `= (2^n xx 16 - 8 xx 2^n)/2^(n + 2 - 1)`

          `= (2^n (16 - 8))/2^(n + 1)`

          `= (2^n xx 8)/(2^n xx 2^1)`

          `= 8/2`

          `= 4`  Ans.
