Final answer:
The value of the expression |3c| without using absolute value notation is 3c.
Step-by-step explanation:
The absolute value of a number is a non-negative value representing the distance of the number from zero on the number line. The expression |3c| represents the absolute value of the product of 3 and c, where c is a positive number. To rewrite this expression without using absolute value notation, we simply remove the absolute value bars and keep the expression inside them intact. Therefore, the correct answer is 3c.
