\(\left(5x-2\right).6^3=3.6^5\)
( 5x -2 ) .216 = 23 328
5x - 2 = 23 328 : 216
5x -2 = 108
5x = 108 + 2
5x = 110
x = 110 : 5
x = 22
Vậy x = 22
( 5x - 2 ) . \(6^3\) = 3. \(6^5\)
=> ( 5x - 2 ). 216= 23328
=> ( 5x - 2 ) = 23328 : 216
=> ( 5x - 2) = 108
=> 5x = 108 + 2
=> 5x = 110
=> x = 110 : 5
=> x = 22
Vậy x = 22
\((5x−2)6^3=3.6^5\)

\(\text{5x - 2 = 23 328 : 216}\)
\(\text{5x -2 = 108}\)
\(5x = 108 + 2\)
\(5x = 110\)
\(x = 110 : 5\)
\(x = 22\)
\(\Rightarrowđpcm\)
\(\left(5x-2\right)6^3=3.6^5\)
=> (5x - 2 ):3=\(6^5:6^3\)
=>(5x -2) : 3 = \(6^{5-3}\) = \(6^2\)
=>(5x-2):3=36
=>5x-2 =36 x 3
=> 5x -2 = 108
=> 5x =108+2
=>5x =110
=> x=110:5
=>x=22
