Řešení rovnice v reálných číslech
Řeš v \( \mathbb{R} \) rovnici:
\( \large 8\sqrt {x + 11} + \sqrt {x-11} = 7\sqrt {x + 21} + 4\sqrt {x-21} \)
\( \large K = \left \{ {\Large \frac{{65}}{3}\large } \right \} \)
\( \large K = \left \{ {\Large \frac{{67}}{3}\large } \right \} \)
\( \large K = \left \{ {\Large \frac{{61}}{3}\large } \right \} \)
\( \large K = \left \{ {\Large \frac{{65}}{4}\large } \right \} \)
