Find the product by suitable identity (x + 1/x) (x - 1/x) (x 2 + 1/x 2 ) (x 4 + 1/x 4 )
Answers
Given,
A given algebraic expression = (x + 1/x) (x - 1/x) (x ^ 2 + 1/x ^ 2 ) (x ^ 4 + 1/x ^ 4 )
To find,
The product of the given expression.
Solution,
We can simply solve this mathematical problem using the following process:
For two variables "a" and "b", an algebraic identity is such that,
(a+b)(a-b) = a^2 - b^2 (Identity 1)
Now, we can evaluate the given expression as follows:
(x + 1/x) (x - 1/x) (x ^ 2 + 1/x ^ 2 ) (x ^ 4 + 1/x ^ 4 )
= {(x + 1/x) (x - 1/x)} (x ^ 2 + 1/x ^ 2 ) (x ^ 4 + 1/x ^ 4 )
= {(x ^ 2 - 1/x ^ 2 )(x ^ 2 + 1/x ^ 2 )} (x ^ 4 + 1/x ^ 4 )
(By using the identity 1)
= {(x ^ 4 - 1/x ^ 4 )(x ^ 4 + 1/x ^ 4 )}
(By using the identity 1)
= x^8 - 1/x^8 (By using the identity 1)
Hence, the final product of the given algebraic expression is equal to x^8 - 1/x^8.
