Question

If x=√3+√2 upon √3_√2,find x²+1/x²​

Answer 1

Hii guys here is your answer

we have equation

x=√3+√2 /√3-√2

• we have to find x^2+1/x^2
• so put the value of x in equation
• x^2+1/x^2
• (√3+√2)^2+1/(√3-√2)^2

we can write it

(√3) ^2+(√2)^2+1/(√3) -(√2) ^2

3+2+1/3-2

=5+1/1

on taking LCM our answer comes

6/1=6

so our answer is( 6)
