Question

(5x-2).6^3=3.6^5 toan 6

Answer 1

\(\left(5x-2\right).6^3=3.6^5\)

( 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

Answer 2

( 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

Answer 3

\((5x−2)6^3=3.6^5\)

\(\text{(5x - 2)216 = 23328}\)

\(\text{5x - 2 = 23 328 : 216}\)

\(\text{5x -2 = 108}\)

\(5x = 108 + 2\)

\(5x = 110\)

\(x = 110 : 5\)

\(x = 22\)

\(\Rightarrowđpcm\)

Answer 4

\(\left(5x-2\right)6^3=3.6^5\)

=> (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
