Question

(3x-6).3= 3 mũ 4

Answer 1

3x-6=81:3=27

3x=27+6

3x=33

x=33:3

x=11 k nha

Answer 2

(3x-6).3=\(3^4\)

(3x-6).3=81

3x-6=81:3

3x-6=27

3x=27+6

3x=33

x=33:3

x=11

nha bn k cho mình mình tích lại

Answer 3

( 3 . x - 6 ) . 3 = 54

  3 . x - 6 = 54 : 3

  3 . x - 6 = 18

  3 . x      = 18 + 6

  3 . x      = 24

       x      = 24 : 3

       x      = 8

Answer 4

\(\left(3x-6\right).3=3^4\)

\(\Rightarrow\left(3x-6\right)=3^4:3\)

\(\Rightarrow3x-6=3^3=27\)

\(\Rightarrow3x=27-6\)

\(\Rightarrow3x=21\)

\(\Rightarrow x=21:3=7\)

tíc mình nha
