B = \(\frac{\frac{1}{2^{10}}.5-\frac{1}{\left(2^2\right)^5}.3}{\frac{1}{2^{10}}.\frac{1}{3}-\frac{1}{2^{11}}}=\frac{\frac{1}{2^{10}}.\left(5-3\right)}{\frac{1}{2^{10}}.\left(\frac{1}{3}-\frac{1}{2}\right)}=\frac{2}{\left(-\frac{1}{6}\right)}=2:\left(-\frac{1}{6}\right)=-12\)
1) tự làm (thực hiện từ dưới lên)
2) B = \(\frac{\left(\frac{1}{2}\right)^{10}.5-\left(\frac{1}{4}\right)^5.3}{\frac{\frac{1}{1024}.1}{3}-\left(\frac{1}{2}\right)^{11}}\)
= \(\frac{\left(\frac{1}{2}\right)^{10}.5-\left(\frac{1}{2}\right)^{10}.3}{\left(\frac{1}{2}\right)^{10}.\frac{1}{3}-\left(\frac{1}{2}\right)^{10}.\frac{1}{2}}\)
= \(\frac{\left(\frac{1}{2}\right)^{10}.\left(5-3\right)}{\left(\frac{1}{2}\right)^{10}.\left(\frac{1}{3}-\frac{1}{2}\right)}\)
= \(\frac{2}{-\frac{1}{6}}\)= 2 . (-6) = -12
1) \(5+\frac{1}{1+\frac{1}{1+\frac{2}{1+\frac{3}{4}}}}=5+\frac{15}{7}=\frac{5}{1}+\frac{15}{7}=\frac{50}{7}\)
vậy 1/6 của bn chắc là đúng rồi, vì lp mik nhiều bn làm như vậy hơn
\(\Rightarrow B=\frac{\left(\frac{1}{2}\right)^{10}.5-\left(\frac{1}{2}\right)^{10}.3}{\left(\frac{1}{2}\right)^{10}.\frac{1}{3}-\left(\frac{1}{2}\right)^{10}.\left(\frac{1}{2}\right)}\) \(\Rightarrow B=\frac{\left(\frac{1}{2}\right)^{10}.\left(5-3\right)}{\left(\frac{1}{2}\right)^{10}.\left(\frac{1}{3}-\frac{1}{2}\right)}\) \(\Rightarrow B=\frac{\left(\frac{1}{2}\right)^{10}.2}{\left(\frac{1}{2}\right)^{10}.\left(-\frac{1}{6}\right)}=-12\)
\(4^5.3^2+2^{10}-2^3.30\)
\(=\left(2^2\right)^5.3^2+2^{10}-2^3.2.15\)
\(=2^{10}.9+2^{10}-2^4.15\)
\(=2^4.\left[\left(2^6.9-2^6\right).15\right]\)
\(=2^4.\left[2^6.\left(9-1\right).15\right]\)
\(=2^4.\left[2^6.2^3.15\right]\)
\(=2^{13}.15\)
45.32 + 210 - 23.30
= 213.15
