Question

Which expression is not equivalent to 8 · x · 2 · y?

a.8x + 2y
b.16yx
c.16xy

Answer 1

a.8x+2y is the correct answer.

Answer 2

Answer:

8x +2y is not equivalent to the given expression.

Step-by-step explanation:

We have been given the expression 8 · x · 2 · y. We have two constants and two variables in this expression. The constants are 8 and 2 and the product of these two numbers is 16.

x and y are variables and the product of these numbers is xy.

Therefore, the resultant expression is given by

8 · x · 2 · y = 16xy

we can rewrite the result as 16yx using commutative property of multiplication.

Thus, we have

8 · x · 2 · y = 16xy = 16yx

Therefore, the expression 8x+2y is not equivalent to 8 · x · 2 · y
