12√18÷2√3

 

12 sqrt[2 x 9] / 2sqrt(3)

3x12sqrt(2) / 2sqrt(3)

36sqrt(2) / 2sqrt(3)      divide both sides by 2

18sqrt(2) / sqrt(3)        multiply both numerator and denominator by sqrt(3)

18sqrt(6) / 3                 divide   .....................................................by 3

=6sqrt(6)

\(\frac{12\sqrt{18}}{2\sqrt{3}}=\frac{36\sqrt{3}}{2\sqrt{3}}=\frac{36}{2}=18\)
