Question

plzzz solve it plzz i will mark as brainliest​

Answer 1

Answer:

18+ 12√2

Step-by-step explanation:

x = 3 + 2√2

x^2 = (3+2√2)^2

= 17+12√2......(I)

x^2 + 1/x^2

= (x^4 + 1)/x^2

putting values from (I)

= [(17+12√2)(17+12√2) + 1] / (17+12√2)

= 17+12√2 + 1

( because we cut one of the 17+12√2 with the denominator hence leaving only one)

= 18 + 12√2
