Question

Select the correct verbal description for the expression below. x(2y+4z)^2

a. the product of x and a factor depending on x

b. the sum of x and a factor not depending on x

c. the sum of x and a factor depending on x

d. the podcut of x and a factor not depending on x

Answer 1

Consider the expression
`x(2y+4z)^2.` This expression is equivalent to the expression

`x\cdot (2y+4z)^2.`

This expression contains two factors:

1 factor:
`x;`

2 factor:
`(2y+4z)^2.`

The second factor does not contain x (is not depending on x), then the expression
`x(2y+4z)^2` is the product of x and a factor not depending on x.

Answer: correct choice is D
