500-50x6
bằng bao nhiêu ai tích mình mình tích lại
tìm x biết:
3x5x=60x58+15x254
\(3\cdot5^x=60\cdot5^8+15\cdot25^4\)
\(3\cdot5^x=60\cdot5^8+15\cdot5^8\)
\(3\cdot5^x=5^8\left(60+15\right)\)
\(3\cdot5^x=5^8\cdot75\)
\(5^x=5^8.75:3\)
\(5^x=5^8.25=5^8.5^2=5^{10}\)
\(\Rightarrow x=10\)

Tìm x biết \(\dfrac{4^5+4^5+4^5+4^5}{3^5+3^5+3^4}.\dfrac{6^5+6^5+6^5+6^5+6^5+6^5}{2^5+2^5}\)=2\(2^x\)
Sửa đề: 3^5+3^5+3^5; 2^x
=>\(2^x=\dfrac{4^5\cdot4}{3^5\cdot3}\cdot\dfrac{6^5\cdot6}{2^5\cdot2}\)
=>\(2^x=\left(\dfrac{4}{3}\right)^6\cdot\left(\dfrac{6}{2}\right)^6=4^6=2^{12}\)
=>x=12
