Giúp mình câu 57 58 59 với
Giải chi tiết giúp mình câu 23, 28, 29, 38, 57, 58, 59, 60, 61, 62, 63, 64 với ạ
mình làm vài câu cho bạn tham khảo,các câu còn lại thì bạn làm tương tự thôi
23.\(\sqrt{14-2\sqrt{33}}=\sqrt{\left(\sqrt{11}\right)^2-2.\sqrt{11}.\sqrt{3}+\left(\sqrt{3}\right)^2}\)
\(=\sqrt{\left(\sqrt{11}-\sqrt{3}\right)^2}=\left|\sqrt{11}-\sqrt{3}\right|=\sqrt{11}-\sqrt{3}\)
28. \(\sqrt{25-4\sqrt{6}}=\sqrt{\left(2\sqrt{6}\right)^2-2.2\sqrt{6}.1+1^2}=\sqrt{\left(2\sqrt{6}-1\right)^2}\)
\(=\left|2\sqrt{6}-1\right|=2\sqrt{6}-1\)
29.\(\sqrt{14-8\sqrt{3}}=\sqrt{14-2\sqrt{48}}=\sqrt{\left(\sqrt{8}\right)^2-2\sqrt{6}.\sqrt{8}+\left(\sqrt{6}\right)^2}\)
\(=\sqrt{\left(\sqrt{8}-\sqrt{6}\right)^2}=\left|\sqrt{8}-\sqrt{6}\right|=\sqrt{8}-\sqrt{6}\)
90 : 10 =
59 * 59 =
70-58=
96*199=
199 * 199 =
987 * 57=
Giúp mình nhé
90 : 10 = 9
59 x 59 =3481
70 - 58 = 12
96 x199 = 19104
199 x 199 = 39601
987 x 57 =56259
\(90\div10=9\) \(59\times59=3481\)
\(70-58=12\) \(96\times199=19104\)
\(199\times199=39601\) \(987\times57=56259\)
