\(3^x=3\cdot3^2\cdot3^3\cdot3^4\cdot3^5\cdot...\cdot3^{99}\cdot3^{100}\)
Rút gọn biểu thức sau:
B = \(3\cdot3^2\cdot3^3\cdot3^4\cdot...\cdot3^{100}\).
bài 1
A =\(\frac{3^7\cdot17-3^9}{2^3\cdot3^5}\)
B=\(\frac{\left(3\cdot4\cdot2^{16}\right)^2}{11\cdot2^{13}\cdot4^{11}-16^9}\)
C =\(\frac{11\cdot3^{22}\cdot3^7-9^{15}}{\left(2\cdot3^{14}\right)^2}\)
Tính\(\frac{-3}{1\cdot2\cdot3}+\frac{-3}{2\cdot3\cdot4}+\frac{-3}{3\cdot4\cdot5}+...+\frac{-3}{18\cdot19\cdot20}\)
A= \(\frac{3}{1\cdot2\cdot3}\cdot\frac{3}{2\cdot3\cdot4}............................\frac{3}{18\cdot19\cdot20}\)
Rút gọn rồi quy đồng:
\(\frac{7}{2^4\cdot3^2}và\frac{11}{2^3\cdot3^3\cdot5}\)
Tính:
\(\frac{2^3\cdot3}{2^2\cdot3^2\cdot5}\)
