Question

if x-1/x = 4 , then find the value of x^2-1/x^2​

Answer 1

Answer:

x-1/x=4

=>x-1=4x

=>3x=-1

=>x=-1/3

Therefore x⁴+1/x⁴=[-1/3]⁴+1/[-1/3]⁴

=1/81+1/1/81

=82/81/1/81=82

Answer 2

Answer:

18

Step-by-step explanation:

HEY THERE IS NO ANSWER FOR THE ABOVE QUESTION

I CAN FIND ANSWER ONLY TO FIND x² + 1/x²

x - 1/x = 4

(x - 1/x)² = (4)²

x² + 1/x² - (2 × x × 1/x) = 16

x² + 1/x² - 2 = 16

x² + 1/x² = 16 + 2

x² + 1/x² = 18
