Re: BdMO National 2012: Higher Secondary 09, Secondary 10
এমনে করা যায়? প্রতি সাইডে দুইটা করে থাকলে মোট বর্গ ৩টা। তাই $2^2-1$........same at $3\times 3-1$.......so $2^k \times 2^k -1$
$\Longrightarrow 2^{2k} - 1\Longrightarrow (2^k)^2 -1$ ........
$\Longrightarrow 2^{2k} - 1\Longrightarrow (2^k)^2 -1$ ........
