simplifie sqrt(8)
Let's reduce: <math><msqrt><mn>8</mn></msqrt></math>
 <math><mn>2</mn><mo>×</mo><msqrt><mn>2</mn></msqrt></math>

The approximate value of: <math><mn>2</mn><mo>×</mo><msqrt><mn>2</mn></msqrt></math> is:
 <math><mn>2</mn><mo>×</mo><mo>≈ </mo><mn>1.4142</mn></math>
 <math><mo>≈ </mo><mn>2.8284</mn></math>
