Step-by-Step Solution

To solve the expression 3614416 \sqrt{\frac{36}{144}} \cdot \sqrt{\sqrt{16}} , follow these steps:

  • Simplify 36144\sqrt{\frac{36}{144}}:
    - Evaluate the fraction: 36144=14\frac{36}{144} = \frac{1}{4}.
    - Take the square root: 14=12\sqrt{\frac{1}{4}} = \frac{1}{2} because 1=1\sqrt{1} = 1 and 4=2\sqrt{4} = 2.
  • Simplify 16\sqrt{\sqrt{16}}:
    - First evaluate the inner square root: 16=4\sqrt{16} = 4 since 42=164^2 = 16.
    - Then take the square root of the result: 4=2\sqrt{4} = 2 since 22=42^2 = 4.
  • Multiply the results from both parts:
    - Multiply the simplified results: 122=1\frac{1}{2} \cdot 2 = 1.

Therefore, the solution to the expression is 11.
