  • can't you just find the square root of a positive number and then make it the opposite???

  • @GnrlTuna Well, sort of. But we can't think of it as the opposite because the opposite would be a negative number and negatives are in the real number system. You can think of it as just taking the square root of the positive number and then make sure to account for the negative by using "i".
