Find the constant term in the expansion of \[\Big(2z - \frac{1}{\sqrt{z}}\Big)^9.\]
Find the constant term in the expansion of
$\Big(x^2+\frac{1}{x}\Big)^4$
By the Binomial Theorem, the constant term in the expansion of $(2z - 1/\sqrt{z})^9$ is 1344.
Again by the Biniomal Theorem, the constant term in the expansion of $(x^2 + 1/x)^4$ is 6.
