Question

if x is if x is equal to 2 root 3 + 2 root 2 find the value of one upon x x plus one upon X and X square + 1 upon x square​

Answer 1

Answer:

Step-by-step explanation:

x = 2+√3

fill the value of X in the equation

x²+1/x²

= (2+√3)²+1/(2+√3)²

= (2)²+(√3)²+2(2)(√3)+1/(2)²+(√3)²+2(2)(√3)

= 4+3+4√3+1/4+3+4√3

= 7+4√3+1/7+4√3

= (7+4√3)²+1/7+4√3

= 49+48+8√3+1/7+√3

= 98+8√3/7+√3

Answer 2

$\huge\purple{Αɳʂɯҽɾ}$

→ a = 2+√3

→ fill the value of x in the equation

→ x²+1/x²

→ (2+√3)²+1/(2+√3)²

→ (2)²+(√3)²+2(2)(√3)+1/(2)²+(√3)²+2(2)(√3)

→ 4+3+4√3+1/4+3+4√3

→ 7+4√3+1/7+4√3

→ (7+4√3)²+1/7+4√3

→ 49+48+8√3+1/7+√3

→ 98+8√3/7+√3
