\(0,1+\dfrac{16}{9}+11,1-\dfrac{20}{9}\)
\(=0,1+11,1-\dfrac{4}{9}\)
\(=11,2-\dfrac{4}{9}=\dfrac{56}{5}-\dfrac{4}{9}=\dfrac{56\cdot9-4\cdot5}{45}=\dfrac{484}{45}\)
\(0,1+\dfrac{16}{9}+11,1-\dfrac{20}{9}\)
\(=0,1+11,1-\dfrac{4}{9}\)
\(=11,2-\dfrac{4}{9}=\dfrac{56}{5}-\dfrac{4}{9}=\dfrac{56\cdot9-4\cdot5}{45}=\dfrac{484}{45}\)

giúp mình với, mik tick cho
Tính: \(E=\dfrac{\left(\dfrac{1}{2}-1\right).\left(\dfrac{1}{3}-1\right)...\left(\dfrac{1}{2002}-1\right).\left(\dfrac{1}{2003}-1\right)}{\dfrac{3}{4}.\dfrac{8}{9}.\dfrac{15}{16}...\dfrac{9999}{10000}}\)
Giải chi tiết giúp mình nha. Thanks
a. -1, 2 + (-0, 8) + 0, 25 + 5,75 -2021 b. -0, 1 + 16/9 + 11,1 + -20/9
(\(\sqrt{\dfrac{9}{4}}\) - \(\sqrt{9}\) ) . \(\sqrt{1\dfrac{9}{16}}\)
Tính nhanh giúp mik nha, mik cần gấp
tính
a) A = \(\dfrac{6^3+3.6^2+3^3}{-13}\)
b) B =\(\dfrac{2.8^4.27^2+4.6^9}{2^3.6^7+2^7.40.9^4}\)
c) C=\(\dfrac{5.4^{15}.9^9-4.3^{20}.8^9}{5.2^{16}.6^{19}-7.2^{29}.27^6}\)
a, \(5^6\) : \(5^5\) + \(\left(\dfrac{4}{9}\right)^0\) b,\(\left(\dfrac{3}{7}\right)^{21}\) : \(\left(1-\dfrac{40}{49}\right)^3\) c, 3.\(\left(\dfrac{2}{3}\right)^3\) -\(\left(\dfrac{-52}{3}\right)^0\) +\(\dfrac{4}{9}\)
