$\left\{ -12,-6,-\sqrt4,0,6 \right\}$

Work Step by Step

$\bf{\text{Solution Outline:}}$ Use the definition of integers. $\bf{\text{Solution Details:}}$ Integers are the numbers $\{...-3,-2,-1,0,1,2,3,...\}.$ These are numbers without decimal values. Hence, the integers of the given set, $ K=\left\{ -12,-6,-0.9,-\sqrt{7},-\sqrt4,0,\dfrac{1}{8}, \dfrac{\pi}{4},6,\sqrt{11} \right\} $ are \begin{array}{l}\require{cancel} \left\{ -12,-6,-\sqrt4,0,6 \right\} .\end{array}
