Answer: 17abc.
Step-by-step explanation: The expression 17(abc) means that the number 17 is being multiplied by the variable expression abc. To simplify this expression, you can simply rewrite it without the parentheses.
To do this, you can distribute the 17 to each term inside the parentheses. Distributing means multiplying each term inside the parentheses by the number outside the parentheses.
So, when you distribute 17 to each term inside the parentheses, you get:
17 * a * b * c
This simplifies to:
17abc
Therefore, the simplified expression is 17abc.
