This is an error in the Algebra Solutions Manual
Mary asked,
In Algebra 1, chapter 5 lesson 1 problem 10x, the answer key says the answer is true for all positive integers. But isn’t it true for all integers? 1 to the power of x =1. If it is a negative power, it is still one, right?

Just for completeness sake – my goto math tool is Wolfram – so here is there answer.
