Question

Buna BRAINLY! Cum se face acest exercitiu : radical din 1 pe 4 + radical 1 pe 9 + radical din 49 pe 36.

Answer 1

√1/√4+√1/√9+√49/√36=1/2+1/3+7/6
aduce la acelasi numitor,adica 6,si aplificand obtinem:
3/6+2/6+7/6=12/6=2

Answer 2

$\displaystyle \sqrt{\frac{1}{4}}+ \sqrt{ \frac{1}{9} }+ \sqrt{ \frac{49}{36} }= \frac{\sqrt{1}}{\sqrt{4}}+ \frac{\sqrt{1}}{\sqrt{9}}+ \frac{\sqrt{49}}{\sqrt{36}}= \frac{1}{2}+ \frac{1}{3}+ \frac{7}{6}= \frac{3+2+7}{6}= \\ \\ \\ = \frac{12}{6}=2.$
