\(\frac{4^5+4^5+4^5}{3^5+3^5+3^5}\cdot\frac{6^5+6^5+6^5+6^5+6^5+6^5}{2^5+2^5}=8^x\)
\(\Rightarrow\frac{3\cdot2^{10}}{3^6}\cdot\frac{6^6}{2^6}=8^x\)
\(\Rightarrow\frac{4^5}{3^5}\cdot3^6=8^x\)
\(\Rightarrow4^5\cdot3=8^x\)
hình như sai đề hoặc mik làm sai:))
\(\frac{4^5+4^5+4^5}{3^5+3^5+3^5}\cdot\frac{6^5+6^5+6^5+6^5+6^5+6^5}{2^5+2^5}=8^x\)
\(\frac{3\cdot4^5}{3\cdot3^5}\cdot\frac{6\cdot6^5}{2\cdot2^5}=8^x\)
\(\frac{4^5}{3^5}\cdot\frac{6^6}{2^5}=8^x\)
\(\left(\frac{4}{3}\right)^5\cdot\left(\frac{6}{2}\right)^6=8^x\)
\(\frac{4^5}{3^5}\cdot3^6=8^x\)
\(4^5\cdot3=8^x\)
\(1024\cdot3=8^x\)
\(3072=8^x\)
\(\Rightarrow\text{ }x\in\varnothing\)
