a) [tex]\sqrt{15}[/tex]

Explicație pas cu pas:

 [tex]a)\sqrt{15}=3,87\\\\b)3\sqrt{2}=4,24\\c)4=4\\d)2\sqrt{5} =4,47[/tex]

Vom introduce factorii sub radical:

[tex]\it a=\sqrt{15}\\ \\ b=3\sqrt2=\sqrt{18}\\ \\ c=4=\sqrt{16}\\ \\ d=2\sqrt5=\sqrt{20}[/tex]

[tex]\it \sqrt{15}<\sqrt{16}<\sqrt{18}<\sqrt{20}\\ \\ Cel\ \ mai\ \ mic\ \ este\ \ \sqrt{15}[/tex]
