Answer

true

Work Step by Step

Natural numbers are the counting numbers $1, 2, 3, ..., 10, 11, 12, 13, ...$. Thus, the natural numbers greater than 10 are $11, 12, 13, ...$. This means that the set on the left side is $\left\{11, 12, 13, ...\right\}$. Two sets are equal if they have exactly the same elements. Note that $\left\{11, 12, 13, ...\right\} = \left\{11, 12, 13, ...\right\}$. The two sets have exactly the same elements therefore they are equal sets. Thus, the given statement is true.
