This week’s problem is offered more in the spirit of a light and pleasant diversion — I don’t think you’ll need any deep insight to solve it. (A little persistence may come in handy though!)

Define a triomino to be a figure congruent to the union of three of the four unit squares in a square. For which pairs of positive integers is an rectangle tileable by triominoes?

TristanAn $m\times n$ rectangle is tileable by triominoes if and only if $m>1$ and $n>1$ (obviously), and $6\mid mn$.

pasangduafoe many situations can be applied the idea of series and particular aspects of series consider prof dr mircea orasanu and prof drd horia orasanu as followed for example in case of logarithmic polynomial as the form L;/L = that appear in sum of fraction ak/z-zk and then as an expression of hypergeometric equation and series ,and CONSTRAINTS OPTIMIZATIONS fact admitted by prof dr Constantin Udriste
