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