Mg các bạn giúp mik ạ
Cảm ơn ạ
Tính:\(\left(-\frac{1}{3}+\frac{5}{6}\right)^2-\frac{-\sqrt{25^2}-\sqrt{49^2}}{\sqrt{36^2+\sqrt{38^2}}}\)
Nhớ giải cho thật kĩ!!
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) \(\frac{2}{3}\sqrt{\frac{81}{16}}-\frac{3}{4}\sqrt{\frac{64}{9}}+\frac{7}{5}.\sqrt{\frac{25}{196}}\)
a,\(\sqrt{49-\sqrt{4+\sqrt{25}}}\)
b,\(\left(\sqrt{100-\sqrt{1}}\right):\sqrt{\left(-3\right)^2}\)
c,\(\sqrt{16+9-\sqrt{25-9}}\)
d,\(\sqrt{\left(-7\right)^2-\sqrt{1^{40}}.\sqrt{16}}\)
a) sqrt{9}+sqrt{4} b) sqrt{0,25}-sqrt{0,01} c) sqrt{frac{16}{25}}-sqrt{frac{1}{81}} d) 2-sqrt{0,36}2. a) sqrt{64}-sqrt{16}+sqrt{left(-3^2right)} b) sqrt{121}+sqrt{left(-5right)^2}-sqrt{9}c) sqrt{frac{9}{4}}-sqrt{frac{16}{36}}-sqrt{49} d) sqrt{left(-4right)^2}+sqrt{left(-5right)^2}-sqrt{left(-6right)^2}
Đọc tiếp
a) \(\sqrt{9}+\sqrt{4}\) b) \(\sqrt{0,25}-\sqrt{0,01}\) c) \(\sqrt{\frac{16}{25}}-\sqrt{\frac{1}{81}}\) d) \(2-\sqrt{0,36}\)
2. a) \(\sqrt{64}-\sqrt{16}+\sqrt{\left(-3^2\right)}\) b) \(\sqrt{121}+\sqrt{\left(-5\right)^2}-\sqrt{9}\)
