Jawaban Terkonfirmasi

$1.3 sqrt{28} -4 sqrt{63} +113=3 sqrt{7.4} -4 sqrt{9.7} + sqrt{113} ,karena \ sqrt{4} =2 dan sqrt{9} =3\2.3 sqrt{7} -3.4 sqrt{7} + sqrt{113}=\ 6 sqrt{7} -12 sqrt{7} + sqrt{113}=-6 sqrt{7} + sqrt{113}\ b. sqrt[3]{2} - sqrt[3]{16} +2 sqrt[3]{54} = sqrt[3]{2} - sqrt[3]{8.2} +2 sqrt[3]{2.27} ,karena\ sqrt[3]{8} =2, sqrt[3]{27} =3\ sqrt[3]{2} - 2sqrt[3]{2} +3.2 sqrt[3]{2} = sqrt[3]{2} - 2sqrt[3]{2} +6 sqrt[3]{2}\=5 sqrt[3]{2}$
