Answer 1

Answer:

$\frac{7}{ \sqrt{7 \sqrt{x} } } \\ = \frac{7}{ \sqrt{7 \sqrt{x} } } \times \frac{ \sqrt{7 \sqrt{x} } }{ \sqrt{7 \sqrt{x} } } \\ = \frac{7 \sqrt{7 \sqrt{x} } }{7 \sqrt{x } } \\ \frac{7 \sqrt{7 \sqrt{x} } }{7 \sqrt{x} } \times \frac{ \sqrt{x} }{ \sqrt{x} } \\ = \frac{7 \sqrt{x} \sqrt{7 \sqrt{x} } }{7x}$

This answer assumes x to be rational.
