Question

calcule as raízes não exatadas das raízes abaixo A)0,09 B)2,25 C)3,24 D)1,69 E)7,29

Answer 1

veja...

$a) \\ \sqrt{0,09} =0,3~~~\mapsto0,3\times0,3=0,09 \\ b) \\ \sqrt{2,25} =1,5~~\mapsto1,5\times1,5=2,25 \\ c) \\ \sqrt{3,24} =1,8~~\mapsto1,8\times1,8=3,24 \\ d) \\ \sqrt{1,69} =1,3~~\mapsto1,3\times1,3=1,69 \\ e) \\ \sqrt{7,29} =2,7~~\mapsto2,7\times2,7=7,29$
