Klaynos Posted June 7, 2006 Share Posted June 7, 2006 specify a negative number. it comes out positive.squaring any real number gives a positive result' date=' the square root of a positive number gives a positive result. if you still think otherwise, start a thread in mathematics. however, taking the square root first will provide a negative number via [b']i[/b]. i've done a lot of work on index laws, and "not just being the inverse of the other" is exactly my point. you cant simplify something unless there are EXACT inverse functions used ^2 is not the exact inverse of ^0.5 so it should not be simplified as such. when my post went through, it was still 5. the refresh button may help. my point is, reductionism can be taken too far and often is. it should be used in moderation and all possibilities thouroughly checked.
