Question

A = (5 $\sqrt{3}$ - 3 $\sqrt{3}$ ) : $\sqrt{12}$ este egal cu numarul natural ...

Answer 1

$A=(5\sqrt{3}-3\sqrt{3}):\sqrt{12} \\ A=(\sqrt{5^{2}*3}-\sqrt{3^{2}*3}):\sqrt{12} \\ A=(\sqrt{75}-\sqrt{27}):\sqrt{12} \\ A=(\sqrt{12}):\sqrt{12} \\ A=\sqrt{12:12} \\ A=\sqrt{1} \\ A=\sqrt{1*1} \\ A=1$
