What is the answer to this equation (9^-6)^3=9

That equation is not a question, and it may not even be an equation.
Let's just check it out and see if it's a true statement.

   (9⁻⁶) ³ = 9⁻¹⁸

So the statement says that  9^-18  is equal to  9 .

It's not.  So the statement is false, and not an equation.

You would have to do order of operations! :)

ill do if u give me points
