(6x^3/3x^4)^2 = (2/x)^2 = 4/x^2
PEMDAS- Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction.
It would be the last one, to inform readers about a topic using facts and details.
(3x +3) (x - 4)
3x(x - 4) + 3(x - 4)
3x^2 - 12x + 3x - 12
3x^2 - 9x - 12
6/9=2/3 because we divide both sides by 3
hope this helps
