12x-33=3³.3³

Answer 1

\(12x-33=3^3.3^3\)

\(12x-33=729\)

\(12x=729+33\)

\(12x=762\)

\(x=762:12\)

\(x=63,5\)

Answer 2

\(12x-33=3^3.3^3\)

\(12x-33=3^6\)

\(12x-33=729\)

\(12x=762\)

\(x=63,5\)

vậy \(x=63,5\)

Answer 3

\(3^3=9\)

12X-33=9*9

12X-33=81

12X=81+33

12X=114

X=114:12

X=57

Answer 4

12x-33=3^3.3^3

12x-33=3^6

12x=3^6+33

12x=762

x=762:12

x=63,5

vậy x=63,5

Answer 5

12x -33 = 3³.3³

^{12x - 33 = 27 .27} 

^{12x - 33 = 729}

^{12x        = 729 - 33}

^{12x        = 696}

 x         = 696 : 12

x          = 58

Answer 6

12x-33=3³  .3³

=>12x-33=3⁶

=>12x=3⁶ - 33 =729-33=696

=> x=696:12

=> x=58

Answer 7

mik lm sai đấy

Answer 8

12x -33 = 3³.3³

12x -33 = 729

12x        = 729 - 33

12x        = 696

    x        = 696 : 12

    x        =  58
