Answer:
Assuming you're referring to a product of two numbers, if one number is decreased by a factor of two and the other is decreased by a factor of eight, the overall effect on the product will depend on the relative values of the two numbers.
Let's say the product is given by P = a * b, where a and b are the two numbers. If we decrease one number by a factor of two, we can write it as 0.5a. Similarly, if we decrease the other number by a factor of eight, we can write it as 0.125b. So the new product, P', can be written as:
P' = (0.5a) * (0.125b)
= 0.0625ab
So the new product will be 1/16th (0.0625) of the original product. This means that the product will be decreased by a factor of 16.
In other words, if you decrease one number by a factor of two and the other by a factor of eight, the resulting product will be 16 times smaller than the original product.
