$138.009 + 341.981 - 146.305 = 123.6 + ?$

The simplified value of the following expression is: $\frac{1}{\sqrt{11-2 \sqrt{30}}}-\frac{3}{\sqrt{7-2 \sqrt{10}}}-\frac{4}{\sqrt{8+4 \sqrt{3}}}$

What is the value of $5 \frac{1}{2} + 7 \frac{1}{2} + 11 \frac{1}{2}$?

If the cube root of $79507$ is $43$,then the value of $\sqrt[3]{79.507} + \sqrt[3]{0.079507} + \sqrt[3]{0.000079507}$ is
