To determine the value of \(\sqrt{91+\sqrt{70+\sqrt{121}}}\), we need to evaluate the expression step by step. 1. Evaluate the innermost square root: \[ \sqrt{121} = 11 \] 2. Substitute and evaluate the next square root: \[ \sqrt{70 + \sqrt{121}} = \sqrt{70 + 11} = \sqrt{81} \] \[ \sqrt{81} = 9 \] 3. Substitute and evaluate the outermost square root: \[ \sqrt{91 + \sqrt{70 + \sqrt{121}}} = \sqrt{91 + 9} = \sqrt{100}…Read More
