\(321- \sqrt{721} + \sqrt{42} + \sqrt{52} - \sqrt{1021} + \sqrt{21} - \sqrt{24} + \sqrt{28}\)
Answered by GPT 3.5
Apologies for the confusion. Let's simplify the expression step by step.

We are given:

\(321 - \sqrt{721} + \sqrt{42} + \sqrt{52} - \sqrt{1021} + \sqrt{21} - \sqrt{24} + \sqrt{28}\)

Using a calculator or simplifying each term separately:

\(321 \approx 321\)

\(\sqrt{721} \approx 26.863\)

\(\sqrt{42} \approx 6.481\)

\(\sqrt{52} \approx 7.211\)

\(\sqrt{1021} \approx 31.953\)

\(\sqrt{21} \approx 4.583\)

\(\sqrt{24} \approx 4.899\)

\(\sqrt{28} \approx 5.292\)

Now we can substitute the approximated values into the expression:

\(321 - 26.863 + 6.481 + 7.211 - 31.953 + 4.583 - 4.899 + 5.292\)

Adding and subtracting the terms:

\(= (321) - (26.863) + (6.481 + 7.211 - 31.953 + 4.583 - 4.899 + 5.292)\)

\(= 321 - 26.863 + (-8.513)\)

\(= 294.137 - 8.513\)

\(= 285.624\)

Therefore, the simplified result is approximately 285.624.
