That depends on the values of x and y.
4xy + x3y + yx2 + yx + 3yx = x3y + x2y + 8xy = (xy)(x2y + x + 8)
No, (2xy) and (3yx) are actually like terms. In algebra, like terms are terms that have the same variable factors raised to the same powers. Since (yx) is equivalent to (xy), both terms can be combined or simplified together, resulting in (5xy).
The product of the GCF and LCM is equal to the product of the original two numbers.
No. A cross product is just a way of simplifying a proportion. If the cross product aren't equal, it follows logically that the proportion isn't equal.
It depends on what the dot product is meant to be equal to.
Since the product of two numbers is equal to the product of their GCF and LCM, the GCF of two numbers is equal to their product divided by their LCM and their LCM is equal to their product divided by their GCF.
Yes.
The product of 13 and 2 is equal to 26.
It's equal to its product which is 165
The product is 4,096
The product is: 243
The product is 9
