To add the monomials \(10pqr\) and \(pqr\), you combine the coefficients of the like terms.
Here's the process:
-
Identify the coefficients:
- The coefficient of \(10pqr\) is \(10\).
- The coefficient of \(pqr\) is \(1\) (since \(pqr\) can be written as \(1 \cdot pqr\)).
-
Add the coefficients:
\[ 10 + 1 = 11 \] -
Combine the result with the variable part:
\[ 11pqr \]
Therefore, the sum of the monomials \(10pqr + pqr\) is \(11pqr\).
