(3x²y³{4}z)

when multiplying the variables, do you multiply the x by the x next to the y^{4}z, and the y with the y^{4}? i asked my teacher this question for a similar problem and he said not to. when i asked my dad for with this problem, he said that you do and the answer is -15x^{3}y^{7}z. which method is correct?

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
