Answer 1

Answer:

find the value of x² + (1/x)², if x+1/x=4

answer is above

Answer 2

Answer:

= 14

Step-by-step explanation:

$x+\frac{1}{x}=4 \\\\ squaring \ on \ both \ sides, \\\\ (x+\frac{1}{x})^2=4^2 \\\\ x^2+(\frac{1}{x})^2+2(x)(\frac{1}{x})=16 \\\\ x^2+\frac{1}{x^2} +2=16\\\\ x^2+\frac{1}{x^2} = 16-2 \\\\ x^2+\frac{1}{x^2}=14$
