Step-by-step solution

To solve the expression 6416\frac{\sqrt{64}}{\sqrt{16}}, we will use the square root quotient property, which states:

  • ab=ab\frac{\sqrt{a}}{\sqrt{b}} = \sqrt{\frac{a}{b}}, assuming b0b \neq 0.

Applying this property, we have:

6416=6416\frac{\sqrt{64}}{\sqrt{16}} = \sqrt{\frac{64}{16}}.

Next, we calculate the division within the square root:

6416=4\frac{64}{16} = 4.

Therefore, we now find the square root of 4:

4=2\sqrt{4} = 2.

Hence, the result of the original expression 6416\frac{\sqrt{64}}{\sqrt{16}} is 2\mathbf{2}.
