Nested Square Roots Evaluation

This problem requires simplifying a mathematical expression with multiple nested square roots. We solve it step-by-step, starting from the innermost root and working outwards.

Radical Expression Step-by-Step Solution

  1. Evaluate the innermost square root: $\sqrt{(4)}$.

    Calculation: $ \sqrt{(4)} = 2 $

  2. Substitute this result into the expression $34 + \sqrt{(4)}$.

    Calculation: $34 + 2 = 36$.

    Evaluate the square root: $ \sqrt{36} = 6 $

  3. Substitute this result into the expression $3 + \sqrt{(34+ \sqrt{(4)})}$.

    Calculation: $3 + 6 = 9$.

    Evaluate the square root: $ \sqrt{9} = 3 $

  4. Substitute this result into the expression $46 + \sqrt{(3 + \sqrt{(34+ \sqrt{(4)})})}$.

    Calculation: $46 + 3 = 49$.

    Evaluate the square root: $ \sqrt{49} = 7 $

  5. Substitute this result into the final expression $42 + \sqrt{(46 + \sqrt{(3 + \sqrt{(34+ \sqrt{(4)})})})}$.

    Calculation: $42 + 7 = 49$.

    Evaluate the final square root: $ \sqrt{49} = 7 $

Final Value Determination

The step-by-step simplification confirms that the value of the given nested square root expression is 7.
