Given:

\(\sqrt{(5+\sqrt{(11+\sqrt{(19+\sqrt{(29+\sqrt{(49)})})})})} \)

Formula used:

Sequentially evaluate the square roots from the innermost term.

Calculation:

\(\sqrt{49}\) = 7

\(\sqrt{(29+7)}\) = \(\sqrt{36}\) = 6

\(\sqrt{(19+6)}\) = \(\sqrt{25}\) = 5

\(\sqrt{(11+5)}\) = \(\sqrt{16}\) = 4

\(\sqrt{(5+4)}\) = \(\sqrt{9}\) = 3

∴ The correct answer is option (3).
