You can put this solution on YOUR website! 1. A) Write the sentence (-x)2 ¹ -x2 in words.
In your own words explain why (-x)2 and -x2 are not equivalent. Provide an example to support your explanation.
---
(-x)^2 = (-x)(-x) = x^2
---
-x^2 = -(x)(x)
========================
B) Evaluate
(a) 3x0 = 0
(b) (3x)^0 when x is not 0.
(3x)^0 = 1
==========================
Are the results different? If so, explain in your own words why they are different. If not, then state so.
