giai tiếp nha bạn
Tìm x thuộc Z biết \(\frac{\sqrt{49}}{6}< \left|x-\frac{2}{3}\right|< \frac{26}{\sqrt{81}}\)
Tìm số nguyên x biết
\(\frac{\sqrt{49}}{6}< \left|x-\frac{2}{3}\right|< \frac{26}{\sqrt{81}}\)
1.Tìm x, biết:\(\left|\frac{5}{3}-x\right|\)- \(\left|\frac{-5}{6}\right|\)= \(\frac{-5}{9}\)
2.Tìm số nguyên x, biết: \(\frac{\sqrt{49}}{6}\) < \(\left|x-\frac{2}{3}\right|\)< \(\frac{26}{\sqrt{81}}\)
Tìm số nguyên x biết: \(\frac{\sqrt{49}}{6}< |x-\frac{2}{3}|< \frac{26}{\sqrt{81}}\)
tìm số nguyên x biết
\(\frac{\sqrt{49}}{6}< |x-\frac{2}{3}|< \frac{26}{\sqrt{81}}\)
Tính
a) \(2\sqrt{\frac{25}{16}}-3\sqrt{\frac{49}{36}}+4\sqrt{\frac{81}{64}}\)
b) \(\left(3\sqrt{2}\right)^2-\left(4\sqrt{\frac{1}{2}}\right)^2+\frac{1}{16}.\left(\sqrt{\frac{3}{4}}\right)^2\)
c) \(\frac{2}{3}\sqrt{\frac{81}{16}}-\frac{3}{4}\sqrt{\frac{64}{9}}+\frac{7}{5}.\sqrt{\frac{25}{196}}\)
\(\frac{\sqrt{49}}{6}< |x-\frac{2}{3}|< \frac{26}{\sqrt{81}}\)
Làm giúp mik vs ai nhanh mik tick cho nha!
\(Cho\)\(x=\left(1+\frac{1}{\sqrt{1}}\right)+\left(1+\frac{1}{\sqrt{9}}\right)+\left(\frac{1}{\sqrt{25}}\right)+\left(1+\frac{1}{\sqrt{49}}\right)+\left(1+\frac{1}{\sqrt{81}}\right)\)
\(y=\left(1+\frac{1}{\sqrt{4}}\right)+\left(1+\frac{1}{\sqrt{16}}\right)+\left(1+\frac{1}{\sqrt{36}}\right)+\left(1+\frac{1}{\sqrt{64}}\right)+\left(1+\frac{1}{\sqrt{100}}\right)\)
Tính x.y
Mn ơi, giúp mk nha, mai mk nộp òi!
