Question

x^4+1/x^4 , x^2+1/x^2 = ?
plz its urgents give me the answer​

Answer 1

Explanation:

We can write (a²+b²) as (a-b)²+2.a.b and also as (a+b)²-2.a.b. This is the concept to solve this question.

We can write (a²+b²) as (a-b)²+2.a.b and also as (a+b)²-2.a.b. This is the concept to solve this question.Now coming to your question

We can write (a²+b²) as (a-b)²+2.a.b and also as (a+b)²-2.a.b. This is the concept to solve this question.Now coming to your question(x⁴+1/x⁴)=(x²+1/x²)²-2=23

We can write (a²+b²) as (a-b)²+2.a.b and also as (a+b)²-2.a.b. This is the concept to solve this question.Now coming to your question(x⁴+1/x⁴)=(x²+1/x²)²-2=23i.e,(x²+1/x²)=25

We can write (a²+b²) as (a-b)²+2.a.b and also as (a+b)²-2.a.b. This is the concept to solve this question.Now coming to your question(x⁴+1/x⁴)=(x²+1/x²)²-2=23i.e,(x²+1/x²)=25Now we can write (x²+1/x²) as (x-1/x)²+2

We can write (a²+b²) as (a-b)²+2.a.b and also as (a+b)²-2.a.b. This is the concept to solve this question.Now coming to your question(x⁴+1/x⁴)=(x²+1/x²)²-2=23i.e,(x²+1/x²)=25Now we can write (x²+1/x²) as (x-1/x)²+2i.e,25=(x-1/x)²+2

We can write (a²+b²) as (a-b)²+2.a.b and also as (a+b)²-2.a.b. This is the concept to solve this question.Now coming to your question(x⁴+1/x⁴)=(x²+1/x²)²-2=23i.e,(x²+1/x²)=25Now we can write (x²+1/x²) as (x-1/x)²+2i.e,25=(x-1/x)²+2i.e,(x-1/x)²=23.

We can write (a²+b²) as (a-b)²+2.a.b and also as (a+b)²-2.a.b. This is the concept to solve this question.Now coming to your question(x⁴+1/x⁴)=(x²+1/x²)²-2=23i.e,(x²+1/x²)=25Now we can write (x²+1/x²) as (x-1/x)²+2i.e,25=(x-1/x)²+2i.e,(x-1/x)²=23.Hope it helps you!
