rationalize the denominator

2+ square root of 3 divided by square root of 3

1 answer

To rationalize the denominator of the expression \(\frac{2 + \sqrt{3}}{\sqrt{3}}\), we can multiply the numerator and the denominator by \(\sqrt{3}\). Here are the steps:

  1. Start with the expression: \[ \frac{2 + \sqrt{3}}{\sqrt{3}} \]

  2. Multiply both the numerator and the denominator by \(\sqrt{3}\): \[ \frac{(2 + \sqrt{3}) \cdot \sqrt{3}}{\sqrt{3} \cdot \sqrt{3}} \]

  3. Simplify the denominator: \[ \sqrt{3} \cdot \sqrt{3} = 3 \]

  4. Distribute \(\sqrt{3}\) in the numerator: \[ (2 + \sqrt{3}) \cdot \sqrt{3} = 2\sqrt{3} + 3 \]

  5. Now, we can write the full simplified expression: \[ \frac{2\sqrt{3} + 3}{3} \]

So, the expression \(\frac{2 + \sqrt{3}}{\sqrt{3}}\) rationalized is: \[ \frac{2\sqrt{3} + 3}{3} \]
