Step-by-step explanation :x= √3+√2/√3-√2
x²= (√3+√2/√3-√2)²
using
(a-b)²=a²+b²-2ab
(a+b)²=a²+b²+2ab
x²=(√3)²+(√2)²+2(√3)(√2)/ (√3)²+(√2)²-2(√3)(√2)
3+2+2√6/3+2-2√6
5+2√6/5-2√6
Rationalising the denominator
(5+2√6)²/(5-2√6)(5+2√6)
using
(a+b)²=a²+b²+2ab
(a-b)(a+b)= a²-b²
(5)²+(2√6)²+2(5)(2√6) / (5)²-(2√6)²
25+24+20√6 / 25-24
x²=48+20√6
