I’m pretty sure the coefficient would be 5, sorry if I’m wrong.

3

Step-by-step explanation:

A term is a group of numbers and variables.

In your expression, there are 3 term: 3k, 10, and 5n^3

A coefficient is just the number attached to the variable.

In the term 3k, the first one in your expression, the 3 is the coefficient because it is being multiplied by an unknown, k. There is also another term with a variable in your expression: 5n^3. 5 would be the coefficient because it is being multiplied by an unknown, n, multiplied by itself three times

A constant is just a number.

In your expression, 10 is a constant because it doesn't have a variable, so no matter what the other variables are, that term will always stay 10

Hope this helps :)
