The set $A \cap B$ represents the intersection of sets A and B, which includes all elements that are common to both sets. In this case, the only common element between set A (\{4,5,6\}) and set B (\{5,7,8\}) is 5.

Let U={1,2,3,4,5,6,7,8,9,10}A={4,5,6}B={5,7,8}\begin{array} { l } U = \{ 1,2,3,4,5,6,7,8,9,10 \} \\A = \{ 4,5,6 \} \\B = \{ 5,7,8 \}\end{array}U={1,2,3,4,5,6,7,8,9,10}A={4,5,6}B={5,7,8}​

Let $\begin{array} { l } U = \{ 1,2,3,4,5,6,7,8,9,10 \} \\A = \{ 4,5,6 \} \\B = \{ 5,7,8 \}\end{array}$
