\(=\dfrac{\left[\dfrac{2^{13}\cdot3^{14}}{3^{13}}+\dfrac{3^{18}}{2^{12}}:\dfrac{3^{12}}{2^{24}}\right]}{2^{12}\cdot3^4+2^{12}\cdot3^2}\)
\(=\dfrac{\left[\dfrac{2^{13}}{3}+\dfrac{2^{12}}{3^6}\right]}{2^{12}\cdot3^2\cdot\left(3^2+1\right)}=\dfrac{2^{12}\cdot\left(\dfrac{2}{3}+\dfrac{1}{3^6}\right)}{2^{12}\cdot3^2\cdot10}\)
\(=\left(\dfrac{487}{729}\right):\dfrac{1}{90}=\dfrac{4870}{81}\)
\(a,35:\left(\frac{-5}{3}\right)+2\frac{1}{2}:\left(-\frac{5}{3}\right)=35.\left(-\frac{3}{5}\right)+\frac{5}{2}.\left(-\frac{3}{5}\right)\)
\(=-21+-\frac{3}{2}\)
\(=\frac{-42-3}{2}=-\frac{45}{2}\)
\(b,\frac{10^3+2.5^3+5^3}{55}=\frac{\left(2.5\right)^3+2.5^3+5^3}{5.11}\)
\(=\frac{5^3\left(2^3+2+1\right)}{5.11}\)
\(=\frac{5^2\left(8+2+1\right)}{11}\)
\(=\frac{5^2.11}{11}=5^2=25\)
\(C,\frac{27^2.2^5}{6^6.32^3}=\frac{\left(3^3\right)^2.2^5}{\left(2.3\right)^6.2^5}\)
\(=\frac{3^6}{2^6.3^6}=\frac{1}{2^6}=\frac{1}{64}\)
đăng từng câu nhé bạn
chứ kiểu vậy thì ko có ai giải cho bạn đâu
\(\frac{6^3+3.6^2+3^3}{-13}=\frac{216+3.36+27}{-13}=\frac{216+108+27}{-13}=\frac{351}{-13}=-27\)

1/ \(=-\frac{64}{27}.\frac{243}{32}\)
\(=-\frac{243}{16}\)
2/ \(=\frac{1}{81}.\frac{5361441}{64}\)
\(=\frac{6561}{64}\)
3/ \(=-\frac{2197}{512}.36,71356045\)
\(=-\frac{2048}{13}\)
tíc mình nha
1\(\left(-\frac{4}{3}\right)^3.\left(\frac{9}{16}\right)^5=-\frac{2187}{16384}\)
2\(\left(\frac{1}{3}\right)^4.\left(-\frac{9}{2}\right)^6=\frac{6561}{64}\)
3\(\left(-\frac{13}{8}\right)^3.\left(-\frac{32}{13}\right)^4=-41,00457607\)
