Question

Carl mai mic numar intreg care verifica inecuatia x^2 <11 este

Answer 1

$\text{x}^2 \ \textless \ 11 \Big|\sqrt{} \quad \\ \\ \sqrt{\text{x}^2}\ \textless \ \sqrt{11} \\ \\ |\text{x}|\ \textless \ \sqrt{11} \\ \\ -\sqrt{11}\ \textless \ \text{x}\ \textless \ \sqrt{11} \\ \\ \text{x}\in \Big(-\sqrt{11},\sqrt{11}\Big) \\ \\ \Rightarrow Cel mai mic numar intreg care verifica inecuatia este -\sqrt{9} , adica. -3.$
