Question

ex 10 va rog.. atat am facut si nu mi-a dat bine

Answer 1

A= √(√3-4)^2 + √(√3+1)^2
A= |√3-4| + |√3+1|
A= 4-√3 + √3+1
A= 5 € N

Answer 2

$\displaystyle A= \sqrt{\left( \sqrt{3}-4\right)^2 } + \sqrt{\left( \sqrt{3}+1\right)^2 } \\ \\ A=\left| \sqrt{3} -4\right|+ \left| \sqrt{3} +1 \right|\\ \\ A=4- \sqrt{3} + \sqrt{3} +1 \\ \\ A=4+1\\ \\ A=5 \in N$
