Recently in class (11 math) we explored exponents in negatives. My teacher placed a question on the board and it said 7*1/7^-7 ( 7 times 1 over 7 to the power of -7 ) She said that in order to get rid of a negative, we must imagine that there is an imaginary "1" multipliying the fraction. 1/7^-7 *1 Then we must "flip" the fraction around to eliminate the negative exponent. so it will be 7*1*7^7/1 I am a type of person to want to to know why and how stuff are done, especially in the subject of math. I want to know the reasoning behind. Unfortunately i couldn't ask her that day, and then the weekend came and the problem still remains. So now i know how to get ride of the negative exponent, but will someone explain to me where the imaginary"1" came from and will i be able to do this in any equation where a negative exponent is present?
