Question

Is this equation correct: (x y)3 = x y3 ? Explain why. If it is correct, how can you prove this? If it is incorrect, what should be done to make it right?

Answer 1

try two numbers 2 and 2

Answer 2

Is that:
\[(xy)^{3} = xy^{3}\]

Answer 3

(x y)3 = x y3
it should be
(x y)3 = x 3y3
(x y)3=xy.xy.xy=x.x.x.y.y.y=x3y3

Answer 5

It is incorrect because the cubed would be distributed to both the x and y.
\[(xy)^{3} = x^{3}y^{3}\]
