Answer 1

DẤU CHẤM LÀ NHÂN NHA

Answer 2

12.x-33=3^2.3^3

=>12x-33=3⁵

=>12x-33=243

=>12x=243+33

=>12x=276 <=> x=23

Answer 3

\(12.x-33=3^2.3^3\)

\(12x-33=3^5=243\)

\(12x=243+33\)

\(12x=276\)

\(x=276:12\)

\(x=23\)

Answer 4

\(12\cdot x-33=3^2\cdot3^3\)

\(=12\cdot x-33=243\)

\(\Rightarrow12\cdot x=243+33==276\)

\(\Rightarrow x=276:12\)

\(\Rightarrow x=23\)

Answer 5

12.x-33=3^2.3^3

12.x-33=243

12.x      =243+33

12.x      =    276

      x      =  276:12

      x      =    23.

Answer 6

\(12\cdot x-33=3^2\cdot3^3\)

\(12\cdot x-33=9\cdot27\)

\(12\cdot x-33=243\)

\(12\cdot x=243+33\)

\(12\cdot x=276\)

\(x=\frac{276}{12}\)

\(x=23\)

Answer 7

\(12x-33=3^2.3^3\)

\(12x-33=3^5\)

\(12x-33=243\)

\(12x=276\)

\(x=23\)

Answer 8

12·x−33=32·33

=12·x−33=243

⇒12·x=243+33==276

⇒x=276:12

⇒x=23
