Answer:
[tex]\sqrt{ \frac{1}{4} } = \frac{1}{2}[/tex]
Step-by-step explanation:
Radical rule
[tex]\sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}},\:\quad \:a\ge 0,\:b\ge 0\\\frac{\sqrt{1}}{\sqrt{4}}[/tex]
Apply this rule
[tex]\sqrt{1}=1\\\frac{1}{\sqrt{4}}[/tex]
Square root
[tex]\sqrt{y} = y\frac{1}{2} = \sqrt{4} = 2\\= 2[/tex]
Solve
[tex]= \frac{1}{2}[/tex]
