Question

a) (2x-3).12=6^2

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

Answer 1

a: \(\left(2x-3\right)\cdot12=6^2\)

\(\Leftrightarrow2x-3=3\)

hay x=3

Answer 2

a) (2x-3).12=6²

=> (2x-3).12= 36

=> ( 2x-3)= 36 : 12

=> 2x-3 = 3

=> 2x = 3+3

=> 2x = 6

=> x = 6:2

=> x= 3

b)( 5x - 2 ) . 6³= 3. 6⁵
=> ( 5x - 2 ). 216= 23328

=> ( 5x - 2 ) = 23328 : 216

=> ( 5x - 2) = 108

=> 5x = 108 + 2

=> 5x = 110

=> x = 110 : 5

=> x = 22
