=\(\frac{1}{16}\)
\(\frac{8^2\cdot4^5}{2^{20}}=\frac{64\cdot1024}{1048576}=\frac{65536}{1048576}=\frac{1}{16}\)

=\(\frac{8^2.4^5}{8^2.4^5.16}\)
=\(\frac{1}{16}\)
Tính: \(\frac{8^{20}\cdot4^{20}\cdot3^7}{4^{25}\cdot64^5\cdot9^2}\)
Rút gọn
\(\frac{8^2\cdot4^5}{2^{20}}\)
\(\frac{5^5\cdot20^3-5^4\cdot20^3+5^7\cdot4^5}{\left(20+5\right)^3\cdot4^5}\)hãy tính giá trị của biểu thức trên:
Tính: A=\(\frac{49^{24}\cdot125^{10}\cdot2^8-5^{30}\cdot7^{49}\cdot4^5}{5^{29}\cdot16^2\cdot7^{48}}\)
Tính:
\(\frac{5}{1\cdot2\cdot3}\)+ \(\frac{8}{2\cdot3\cdot4}\)+\(\frac{11}{3\cdot4\cdot5}\)+ ..... +\(\frac{6026}{2008\cdot2009\cdot2010}\)
Các bạn ghi cả cách làm nữa nha
Tìm x biết: \(\frac{1}{1\cdot2\cdot3}+\frac{1}{2\cdot3\cdot4}+\frac{1}{3\cdot4\cdot5}+...+\frac{1}{8\cdot9\cdot10}\cdot x=\frac{22}{45}\)Trình bày cách tính
Tính \(A=\left(\frac{1}{4\cdot9}+\frac{1}{9\cdot14}+\frac{1}{14\cdot19}+...+\frac{1}{44\cdot49}\right)\cdot\frac{1-3-5-7-...-49}{89}\)
\(B=\frac{5\cdot4^{15}\cdot9^9-4\cdot3^{20}\cdot8^9}{5\cdot2^{10}\cdot6^{19}-7\cdot2^{29}\cdot27^6}-\frac{2^{19}\cdot27^3+15\cdot4^9\cdot9^4}{6^9\cdot2^{10}+12^{10}}\)
Tính tổng:\(S=\frac{1}{1\cdot3}-\frac{1}{2\cdot4}+\frac{1}{3\cdot5}-\frac{1}{4\cdot6}+\frac{1}{5\cdot7}-\frac{1}{6\cdot8}+\frac{1}{7\cdot9}-\frac{1}{8\cdot10}\)
Tính:
\(2^4+8\left[\left(-2\right)^2:\frac{1}{2}\right]^0-2^{-2}\cdot4+\left(-2\right)^2\)
