Web3 dec. 2024 · 1 f ( x) = ( x 2 + 1) ( x + 1 x) 10 We can rewrite f ( x) like below: f ( x) = x 2 ( x + 1 x) 10 + ( x + 1 x) 10 In the first term, the power of x, must be − 2 in the parenthesis, so the when it's multiplyed by x 2 the power of x becomes 0. And we know that: ( x + 1 x) 10 = ∑ k = 0 10 ( 10 k) x k ( 1 x) 10 − k So k + k − 10 = − 2 => k = 4. Web29 mrt. 2024 · View solution. Question 2. Views: 5,421. 1.
