Can anyone tell me why are using only one value in option A, ain't there two?
We are given that a = -1. Which other value do you want to check and why? Also, which other value do you suggest satisfies a^a = -|a|?
If, a=1, then there will be two value, |a|=1 or -1, right
then why not the same in the case of a=-1, -|a|=-|-1|, this will come as one positive value and the other as same right?,
i am confused in this only, nothing else, if -1 from the modulus will come as only positive and not as -1
