Question

What is the square root of 1 over 4

Answer 1

0.5 would be the answer to that

Answer 2

`\sqrt{ (1)/(4) } = (1)/(2)`

Explanation:

Radical rule

`\sqrt{(a)/(b)}=(√(a))/(√(b)),\:\quad \:a\ge 0,\:b\ge 0\\(√(1))/(√(4))`

Apply this rule

`√(1)=1\\(1)/(√(4))`

Square root

`√(y) = y(1)/(2) = √(4) = 2\\= 2`

Solve

`= (1)/(2)`
