Is this equation correct: (3 • x • y)4 = 81 • x • y ? Explain why. If it is correct, how can you prove this? If it is incorrect, what should be done to make it right?

The stars that you show in your
equation means multiplication,
but they are not normally shown
in equations; because it is under
stood to mean multiply. The equation
is normally written like this:
4(3XY) = 81XY.
I hope I have answered your question.

This is not an equation; 12XY
DOES NOT EQUAL 81XY.

So would you consider this equation correct if so why and if not why not?

This is correct: 12XY < 81XY, In other
words, 12 apples are less than 81 apples. So this is an inequality.
