Question

calculați
$5 \sqrt{3 + 12 \sqrt{2 - 2 \times 7 \sqrt{2 \times 3 \sqrt{0 - 0 \sqrt{6} } } } }$
​

Answer 1

rad=radical din

rad^5(3+12rad(2-2*7rad(2*3rad(0))))

Radical in 0=0

rad^5(3+12rad(2-2*7rad(2*3*0)))

Evident ca orice inmultit cu 0=0

rad^5(3+12rad(2-2*7rad(0)))

rad^5(3+12rad(2-0))

Rezultat final: rad^5(3+12rad(2))
