Question

if x=2-√3 find the value of (x+1/x)^3​

Answer 1

Answer:

64

Step-by-step explanation:

x=2-root3

(2-root3+1/2-root3)^3

(8-4root3/2-root3)^3

multiple divide by 4

therefore,

(2-root3*4/2-root3)^3

2-root3 gets cancelled

only 4^3 is left which is 64

HOPE U UNDERSTOOD TEXT ME FOR ANY CLARIFICATION XD
