Question

x=radical mare peste 24 la a doua si 32 la a doua. y=radical din 2304. z=radical mare peste (-2) la a doua ori (-3) la a parta . Cat este x-y-z?

Answer 1

[tex]x=\sqrt{24^2+32^2}=\sqrt{576+1024}=\sqrt{1600}=40\\ y=\sqrt{2304}=48\\ z=\sqrt{(-2)^2\cdot (-3)^4}=\sqrt{4\cdot 81}=\sqrt{324}=18\\ x-y-z=40-48-18=\boxed{-26}[/tex]
