simplyfy the following​.

Answer 1

$\sqrt{1728 \div 155 - \sqrt{98 + \sqrt[3]{529 \times \sqrt{529} } } } \\ \\ \sqrt{1728 \div 155 - \sqrt{98 + \sqrt[3]{529 \times23}}} \\ \\ \sqrt{1728 \div 155 - \sqrt{98 +23}} \\ \\ \sqrt{1728 \div 155 - \sqrt{121}} \\ \\ \sqrt{1728 \div 155 - 11} \\ \\ \sqrt{ \frac{1728}{155} - 11 } \\ \\ \sqrt{ \frac{1728 - 1705}{155} } \\ \\ \sqrt{ \frac{ 23}{155} }$
