Question

a) |√2-√3|+|5-2√2| b) |3√5-6|+|1-√5|+|5√5+1| c) |3-√5|+|√3-1|+|√3+√5|​

Answer 1

Răspuns:

Explicație pas cu pas:

a) |√2-√3|+|5-2√2|

√3 - √2 + 5 - 2√2 = 5 + √3 - 3√2

b) |3√5-6|+|1-√5|+|5√5+1|

3√5 - 6 + √5 - 1 + 5√5 + 1 = 9√5 - 6

c) |3-√5|+|√3-1|+|√3+√5|​

3 - √5 + √3 - 1 + √3 + √5 = 2 + 2√3
