what is the sum of √5 and √7

1 answer

The sum of \( \sqrt{5} \) and \( \sqrt{7} \) can be expressed as:

\[ \sqrt{5} + \sqrt{7} \]

This sum cannot be simplified further into a simpler radical form. However, if you want a numerical approximation:

\[ \sqrt{5} \approx 2.236 \quad \text{and} \quad \sqrt{7} \approx 2.646 \]

Adding these gives:

\[ \sqrt{5} + \sqrt{7} \approx 2.236 + 2.646 \approx 4.882 \]

So, the sum \( \sqrt{5} + \sqrt{7} \) is approximately \( 4.882 \).
