​

Answer 1

$\sqrt{15*\sqrt{35} } \\\\\\ \sqrt{\sqrt{15^{2}*35 } } \\\\\sqrt[4]{3^{2}*5^2*5*7 }\\ \\\sqrt[4]{3^2*5^3*7}$

Answer 2

Oie, Td Bom?!

$\sqrt{15 \sqrt{35} }$

$\sqrt{ \sqrt{15 {}^{2} } \sqrt{35} }$

$\sqrt{ \sqrt{15 {}^{2} \times 35} }$

$\sqrt{ \sqrt{35 \times 15 {}^{2} } }$

$\sqrt{ \sqrt{35 \times 225} }$

$\sqrt{ \sqrt{7875} }$

$\sqrt[2 \times 2]{7875}$

$\sqrt[4]{7875} ≊9,42025$
