The term independent of $x$ in the expansion of $\left(x + \frac{1}{x}\right)^{10}$ is:
Step-by-Step Solution
Key Concept: Write the general term $T_{r+1} = \binom{10}{r} x^{10-2r}$, set the exponent of $x$ equal to zero to find the required value of $r$, and then evaluate $\binom{10}{r}$ for that $r$.
