crispyrat:
where i is a thing?
crispyrat:
you may not need them, im not the best at roots
in fact u prib dont
so a odd number of exponents mean the answer is a negative
xXQuintonXx:
im decent at roots but yk positive ones
crispyrat:
that means that
x is a negative
what negative number when multiplied by itself is -1? that means if it was squared it would be positive
