1/27 * 9^24 = 3^(-3) * 3^48 = 3^45 √72 - √18 / √2 = √2*√36 - √2*√9 / √2 = √2(6 - 3) / √2 = 3  GOTOWE!!!

[latex]frac{1}{27}*9^{24} = 3^{-3}*(3^{2})^{24} = 3^{-3}*3^{48} = 3^{(-3+48)}= 3^{45}[/latex] [latex]frac{sqrt{72}-sqrt{18}}{sqrt{2}} = frac{sqrt{36*2}-sqrt{9*2}}{sqrt{2}}=frac{sqrt{36}*sqrt{2}-sqrt{9}*sqrt{2}}{sqrt{2}}=frac{6sqrt{2}-3sqrt{2}}{sqrt{2}} =frac{3sqrt{2}}{sqrt{2}} = 3[/latex]
