Given:

The given inequality is
$√(x) \geq 9$

We need to determine the solution to the inequality.

Solution of the inequality:

The solution of the inequality can be determined by solving the inequality.

Let's equate the inequality.

Thus, we have;

√(x) =9

Squaring on both sides, we get;

x=9^2

Simplifying, we get;

x=81

Let us check the solution in the original expression.

Substituting
x=81 in
$√(x) \geq 9$ , we get;

$√(81)\geq 9$

$9\geq 9$

Thus, the solution satisfies the inequality.

Thus, the solution to the inequality is 81.

Hence, Option E is the correct answer.
