Right.
To find the product of (-3)(5)(-8)(15), you simply need to multiply the numbers together:
(-3)(5)(-8)(15) = -3 * 5 * -8 * 15
To determine the sign of the product, you need to know the following rule of multiplying signed numbers:
When you multiply an odd number of negative numbers, the product is negative. When you multiply an even number of negative numbers, or zero, the product is positive.
In this case, we have four negative signs (-3, -8, -15). Since four is an even number, the product will be positive.
Therefore, the product (-3)(5)(-8)(15) is positive.
The correct answer is A. Positive.
