Answer:
The coefficient of 13 m is 13.
Explanation:
Consider the provided expression.
Numbers appear with variables are called coefficients.
Alphabets in an expression are called variables.
Numbers appear without variables are called Constant terms.
Here we need to identity the coefficient.
From the above definition we know the number appear with the variables are coefficients.
Since m is variable, thus the number 13 must be the coefficient.
Hence, the coefficient of 13 m is 13.
