Question

(-1)X 12 times=(-1) to the 12th power. Will these products be negative or positive?

Answer 1

$(-1)x\times(-1)^{12}\implies -x\times(-1)^{2+2+2+2+2+2} \\\\\\ -x\times(-1)^2 (-1)^2 (-1)^2 (-1)^2 (-1)^2 (-1)^2 \implies -x\times 1\cdot 1\cdot 1\cdot 1\cdot 1\cdot 1\implies -x$

bear in mind that any value raised to an even power, will always positivize.
