Question

respondam a questão 3 pra mim pf, segui em anexo

Answer 1

$\sqrt{0} + \sqrt{1} - \sqrt{ \frac{1}{4} }=$

$0 +1- \frac{1}{2} = \frac{1}{2}$

Answer 2

$\sqrt{0} + \sqrt{1} - \sqrt{ \frac{1}{4} } = 0 + 1 - \frac{1}{2} = 1 - \frac{1}{2} \\ \\ (MMC ) = \frac{1}{1} - \frac{1}{2} = \frac{2-1}{2} = \boxed{ \frac{1}{2} }$
