simplify sqrt(50)
Let's reduce: <math><msqrt><mn>50</mn></msqrt></math>
 <math><mn>5</mn><mo>×</mo><msqrt><mn>2</mn></msqrt></math>

The numeric value of: <math><mn>5</mn><mo>×</mo><msqrt><mn>2</mn></msqrt></math> equals:
 <math><mn>5</mn><mo>×</mo><mo>≈ </mo><mn>1.4142</mn></math>
 <math><mo>≈ </mo><mn>7.0711</mn></math>
