How many rational terms are there in the expansion of binomial (x ^ 2 + 1 / x) ^ 10 (x ^ 2 + 1 / x ^ 10 is not connected in the middle under the third root sign.)

How many rational terms are there in the expansion of binomial (x ^ 2 + 1 / x) ^ 10 (x ^ 2 + 1 / x ^ 10 is not connected in the middle under the third root sign.)

In the expansion of (x ^ 2 + 1 / x under the root of degree 3) ^ 10
(x ^ 2) ^ 3K under the root sign of degree 3 is a rational term
10/3=3...1
There are three rational terms
