\(\left(-3,2\right).\dfrac{-15}{64}+\left(0,8-2\dfrac{4}{15}\right):3\dfrac{2}{3}\)
\(=\left(\dfrac{-16}{5}\right).\dfrac{-15}{64}+\left(\dfrac{4}{5}-\dfrac{34}{15}\right):\dfrac{11}{3}\)
\(=\left(\dfrac{-16}{5}\right).\dfrac{-15}{64}+\left(\dfrac{-22}{15}\right).\dfrac{3}{11}\)
\(=\dfrac{3}{4}+\left(\dfrac{-2}{5}\right)\)
\(=\dfrac{7}{20}\)
\(\left(-3,2\right).\dfrac{-15}{64}+\left(0,8-2\dfrac{4}{15}\right):3\dfrac{2}{3}\)
Giải hộ mik ạ^^
e) \(\left(15-6\dfrac{13}{18}\right)\):\(12\dfrac{1}{27}\)-\(2\dfrac{1}{8}\):\(1\dfrac{11}{40}\)
g) (-3,2).\(\dfrac{-15}{64}\)+\(\left(0,8-2\dfrac{4}{15}\right)\):\(3\dfrac{2}{3}\)
\(\left(-3,2\right).\dfrac{-15}{64}+[0.8-2\dfrac{4}{15}]:3\dfrac{2}{3}\)
(-3,2).-15/64+(0,8-2/4/15):3/2/3
(-3,2)x-15/64+(0,8-2/4/15:3/2/3=
(-3,2) . -15/64 + 0,8-2/4/15 : 3/2/3
đó bạn
thực hiện phép tính sau :
\(\left[\dfrac{\left(0,8\right)^5}{\left(0,4\right)^6}+\dfrac{2^{15}.9^4}{6^6.8^3}\right]:\dfrac{45^{10}.5^{20}}{7^{15}}\)
(-3,2) . -15/64 + ( 0,8 - 2 4/5 ) : 3 2/3
(-3,2)x-15/64+(0,8-2 4/15):3 2/3
