\(4\times\left(\frac{1}{4}\right)^2+25\times\left[\left(\frac{3}{4}\right)^3\div\left(\frac{5}{4}\right)^3\right]\div\left(\frac{3}{2}\right)^3\)
\(2^3+3\times\left(\frac{1}{2}\right)^0-1+\left[\left(-2\right)^2\div\frac{1}{2}\right]-8\)
Tính:
\(\frac{0,8\div\left(\frac{4}{5}\times1,25\right)}{0,64-\frac{1}{25}}+\frac{\left(1,08-\frac{2}{5}\right)\div\frac{4}{7}}{\left(6\frac{5}{9}-3\frac{1}{4}\right)\times2\frac{2}{17}}+\left(1,2\times0,5\right)\div\frac{4}{5}\)

a)\(4\frac{5}{9}:\left(\frac{-5}{7}\right)+\frac{49}{9}:\left(\frac{-5}{7}\right)\)

e)\(\frac{8^{14}}{4^4\times64^5}\)
f)\(\frac{9^{10}\times27^7}{81^7\times3^{15}}\)
Tính : a) \(\frac{1}{9}\div\frac{8}{27}\times-3\div\frac{81}{128}\)
b) \(\frac{\left(13\frac{1}{4}-2\frac{5}{27}-10\frac{5}{6}\right)\times230\frac{1}{25}+46\frac{3}{4}}{\left(1\frac{3}{7}+\frac{10}{3}\right)\div\left(12\frac{1}{3}-14\frac{2}{7}\right)}\)
Tính tổng:
\(B=\left(\frac{-3}{5}+\frac{4}{9}\right)\div\frac{7}{11}+\left(\frac{-2}{5}+\frac{5}{9}\right)\div\frac{7}{11}\)
\(\left(\dfrac{-4}{3}+\dfrac{5}{13}\right)\div\dfrac{2}{7}-\left(\dfrac{9}{4}+\dfrac{8}{13}\right)\div\dfrac{2}{7}\)
\(\frac{3}{4}+\frac{1}{4}\div\left(\frac{-2}{3}\right)-\left(-5\right)\)
\(12\cdot\left(\frac{2}{5}-\frac{5}{6}\right)^2\)
\(\left(-2\right)^2+\sqrt{36}-\sqrt{9}+\sqrt{25}\)
\(\left(9\frac{3}{4}\div3.4\cdot2\frac{7}{34}\right)\div\left(-1\frac{9}{16}\right)\)
