Dau coroana​

Answer 1

$\sqrt{5*\sqrt{25} }+\sqrt{7*\sqrt{49} }-\sqrt{9*\sqrt{16} }  \\\\\sqrt{5*5}+ \sqrt{7*7}-\sqrt{9*4}\\  \\5+7-\sqrt{36}\\ \\12-6\\\\6$

Answer 2

rad5*rad25+rad7*rad49-rad9*rad16=
rad5*5 +rad7rad49-rad9rad16=
rad5*5+rad7*7-rad9rad16=
rad5*5+rad7*7-rad9rad4=
rad5^2 + rad7^2 - 3*2=
5+rad7^2-3*2=
5+7-3*2=
5+7-6=
