The problem asks us to select the expressions that are equivalent to $6m + 5m$.

1. Problem Description

The problem asks us to select the expressions that are equivalent to $6m + 5m$.

2. Solution Steps

First, we simplify the given expression $6m + 5m$ by combining like terms.

$6m + 5m = (6+5)m = 11m$

Now, we compare this simplified expression with the options provided.

- $11m$: This is the same as the simplified expression, so it is equivalent.

- $m \cdot 11$: This is equivalent to $11m$ due to the commutative property of multiplication.

- $m^{11}$: This is $m$ raised to the power of 11, which is not equivalent to $11m$.

- $7m + 5m$: Combining these like terms gives $(7+5)m = 12m$, which is not equal to $11m$.

Therefore, the expressions equivalent to $6m + 5m$ are $11m$ and $m \cdot 11$.

3. Final Answer

The expressions that are equivalent to $6m + 5m$ are $11m$ and $m \cdot 11$.
