Question

Calcule:
a)√1/4
b)√0,09
c)√64/49

Answer 1

a)

$\sqrt{\frac{1}{4}}~=\\\\\\=~\frac{\sqrt{1}}{\sqrt{4}}\\\\\\=~\boxed{\frac{1}{2}~~ou~~0,5}$

b)

$\sqrt{0,09}~=\\\\\\=~\sqrt{\frac{9}{100}}\\\\\\=~\frac{\sqrt{9}}{\sqrt{100}}\\\\\\=~\boxed{\frac{3}{10}~~ou~~0,3}$

c)

$\sqrt{\frac{64}{49}}~=\\\\\\=~\frac{\sqrt{64}}{\sqrt{49}}\\\\\\=~\boxed{\frac{8}{7}}$

Answer 2
