Question

9 + 2 . x = 3 mũ 5 : 3 mũ 2

Answer 1

\(9+2.x=3^5:3^2\)
\(9+2.x=3^3\)
\(9+2x=27\)
\(2x=27-9\)
\(2x=18\)
Vậy \(x=9\)

Answer 2

= 9+2.x=9 

= 2.x=9-9

= 2.x=0

x= 0:2

x=0

Answer 3

9+2 . x = 3³

^{9+2 x = 27}

^{2x      = 27 - 9}

^{2x      = 18}

^{x        = 18 : 2} 

^{x        = 9}

 

Answer 4

9

Answer 5

9+2 . x = 3³

^{9+2 x = 27}

^{2x      = 27 - 9}

^{2x      = 18}

^{x        = 18 : 2} 

^{x        = 9}
