WebWhat Sal is saying is that people try to prove that i = square root (-1) is wrong because they end up with an answer that 1 = -1 which obviously isn't true. But they're wrong because the square root multiplication rule doesn't apply when both numbers are negative. Yes the absolute value of -1 = absolute value of 1. WebPowers offer a very useful way to simplify mathematical notation when we need to multiply a number by itself repeatedly.. If you need to revert the process to find out what number …
