Consider the given inequality,

$\sqrt[]{x}\leq11$

Note that a square root inequality is defined only if the 'x' is non-negative.

$x\ge0$

Now, squaring both sides will not affect the inequality as both sides are positive terms,

$\begin{gathered} (\sqrt[]{x})^2\leq11^2 \\ x\leq121 \end{gathered}$

Combining the two results,

$0\leq x\leq121$

Thus, the solution set to the inequality is the set of all real numbers from 0 to 121 .
