$$6 {4\over 9}$$ % ..???kkk

The value $${7+3\sqrt {5}\over3+\sqrt { 5}}-{7-3\sqrt {5}\over3-\sqrt { 5}}$$ lies between

The value of Let $$\left({\sqrt {1875}\over\sqrt { 3888}}÷{\sqrt {1200}\over\sqrt {768}} \right)\ × \left({\sqrt {175}\over\sqrt {1792}} \right)\ $$. Then $$ \sqrt { x}$$ is equal to:

if $$x=\sqrt {64}+\sqrt {121}-\sqrt {169}$$, the find the value of x²

Simplify the following

  $${\sqrt { 10+{\sqrt { 25+ {\sqrt { 108 +\sqrt { 154+ \sqrt { 225} \ } \ } \ }} \ } } \ }\over \sqrt { 16+ 19.25×4^2} $$

Find the value of the given expression.

 $$\sqrt { 8+\sqrt { 1681} \ } \ $$

If p = 124, $$3\sqrt{p(p^2-3p+3)-1}=?$$

If p = 101, then the value of   $$3\sqrt{p(p^2-3p+3)}$$ is
