B)\(\frac{9^4\cdot49^3\cdot2^5}{21^5\cdot81\cdot6^3}\)
Mình cần gấp , xin các bạn giúp mình
\(A=\frac{1.5\cdot6+2\cdot10\cdot12+3\cdot15\cdot18+4\cdot20\cdot24+5\cdot25\cdot30}{1\cdot3\cdot5+2\cdot6\cdot10+3\cdot9\cdot15+4\cdot12\cdot20+5\cdot15\cdot25}\)
Tính hợp lý
a)\(\left(-\frac{1}{3}\right)^2\cdot\left(5\frac{1}{2}\right)^0+\left(-\frac{1}{3}\right)^5\cdot4\frac{1}{2}\)
b) \(\left(\frac{2^2\cdot2^3}{4^2\cdot16}\right)^{15};\left(\frac{2^6}{16^2}\right)^{10}\)
c)\(\frac{2^{15}\cdot9^4}{6^6\cdot8^3}\)
