Question

Simplify the variable expression: the absolute value of (8)(-z)(-z)(-z). I think the answer is 8z^3. Is that correct?

Answer 1

Close, but no

Answer 2

the three negatives will multiply to get a negative

so

(8)(-z)(-z)(-z) = -8z^3

Answer 3

but it's in the absolute value sign. so that would make it positive. correct?

Answer 4

oh so it's |8||-z||-z||-z| ?

Answer 5

use | | to mean absolute value

Answer 6

it's l(8)(-z)(-z)(-z)l

Answer 7

that would make it positive correct?

Answer 8
