Math Problem Statement

(2 + akar 3) / (akar 3 - akar 2) =

Solution

To solve the expression 2+332\frac{2 + \sqrt{3}}{\sqrt{3} - \sqrt{2}}, we can start by rationalizing the denominator. This involves multiplying both the numerator and the denominator by the conjugate of the denominator.

Steps:

  1. Identify the conjugate of the denominator:
    The conjugate of 32\sqrt{3} - \sqrt{2} is 3+2\sqrt{3} + \sqrt{2}.

  2. Multiply both numerator and denominator by the conjugate: 2+332×3+23+2=(2+3)(3+2)(32)(3+2)\frac{2 + \sqrt{3}}{\sqrt{3} - \sqrt{2}} \times \frac{\sqrt{3} + \sqrt{2}}{\sqrt{3} + \sqrt{2}} = \frac{(2 + \sqrt{3})(\sqrt{3} + \sqrt{2})}{(\sqrt{3} - \sqrt{2})(\sqrt{3} + \sqrt{2})}

  3. Expand the numerator: (2+3)(3+2)=23+22+3+6(2 + \sqrt{3})(\sqrt{3} + \sqrt{2}) = 2\sqrt{3} + 2\sqrt{2} + 3 + \sqrt{6} Simplified, this is: 3+22+23+63 + 2\sqrt{2} + 2\sqrt{3} + \sqrt{6}

  4. Simplify the denominator: The denominator simplifies as the difference of squares: (3)2(2)2=32=1(\sqrt{3})^2 - (\sqrt{2})^2 = 3 - 2 = 1

  5. Final Expression: Since the denominator is 1, the final expression is just the simplified numerator: 3+22+23+63 + 2\sqrt{2} + 2\sqrt{3} + \sqrt{6}

So, the simplified form of 2+332\frac{2 + \sqrt{3}}{\sqrt{3} - \sqrt{2}} is: 3+22+23+6\boxed{3 + 2\sqrt{2} + 2\sqrt{3} + \sqrt{6}}
