Answer:
(√3+√2)²+(√3-√2)².
(√3+√2)².
(a+b)²=a²+b²+2ab.
(√3+√2)²=(√3)²+(√2)²+2(√3)(√2).
=3+2+2√6. (because √3×√2=√6).
=5+2√6.
(√3-√2)².
(a-b)²=a²+b²-2ab.
(√3-√2)²=(√3)²+(√2)²-2(√3)(√2).
=3+2-2√6.
=5-2√6.
(√3+√2)²+(√3-√2)²=(5+2√6)+(5-2√6).
=5+2√6+5-2√6. (because +×-=-).
=5+5.
=10.

Step-by-step explanation:
(a+b)²+(a-b)²
a²+b²+2ab+a²+b²-2ab
2(a²+b²)
Here a=√3 and b=√2
So the answer is 10
2(√3²+√2²)
2(3+2)
2(5)
10
