1)2x=65536
2x=216
=>x=16
2)............
các câu khác bn làm tương tự nhé
1)
\(2^x=4^5.4^3\\ 2^x=\left(2^2\right)^5.\left(2^2\right)^3\\ 2^x=2^{10}.2^6\\ 2^x=2^{10+6}\\ 2^x=2^{16}\\ \Rightarrow x=\pm16\)
2)
\(2^x=32^5.64^6\\ 2^x=\left(2^5\right)^5.\left(2^6\right)^6\\ 2^x=2^{25}.2^{36}\\ 2^x=2^{61}\\ \Rightarrow x=61\)
3)
\(2^x=4^3.8^4.16^5\\ 2^x=\left(2^2\right)^3.\left(2^3\right)^4.\left(2^4\right)^5\\ 2^x=2^6.2^{12}.2^{20}\\ 2^x=2^{6+12+20}\\ 2^x=2^{38}\\ \Rightarrow x=\pm38\)
