Question

Solve
$\sqrt{(3 \div 2 - 1 \div 2) {?}^{2} + ( - 1 \div 2 - 3 \div 2) { }^{2} }$
​

Answer 1

Step-by-step explanation:

$\sqrt{ (\frac{3}{2} - \frac{1}{2} )^{2} + ( \frac{ - 1}{2} - \frac{3}{2} )^{2} } \\ \\ \sqrt{ (\frac{3 - 1}{2} )^{2} + ( \frac{ - 1 - 3}{2} )^{2} } \\ \\ \sqrt{ {(1)}^{2} + { (- 2)}^{2} } \\ \\ \sqrt{1 + 4} \\ \\ \sqrt{5}$
