Question

if x+1by x =2 find x^4+1by x^4​

Answer 1

Answer:

2

Step-by-step explanation:

given

x + 1/x = 2

On squaring we get

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

i.e. x^2 + 1/x^2 = 2

Now again squaring the obtained equation

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

x^4 + 1/x^4 = The answer to the question is 2 .

hence cancel each other out i.e. a= x and b=1/x
