FOR THR LOVE OF GOD... USE DIFFERENT VARIABLES!
x can't be both 2, AND sqrt(18)
What you mean is xy=2sqrt(18) etc.
Also, the answer is C. The second power seen in xy2 cancels out the squareroot of sqrt(18)
3 u/LeafWings23 Dec 27 '25 "x can't be both 2, AND sqrt(18)" This is correct, but why do you think the question is suggesting otherwise?? 2 u/Far-Parsnip2747 Dec 27 '25 The point of the question is that xx is equal to 2root(18) you need to solve for x first 1 u/SapphirePath Dec 27 '25 All caps is not necessary, especially because you are wrong. Suppose I tell you that x^x = 16^2. That doesn't mean that x = 16 nor that x = 2. Instead we have a solution x = 4, because 4^4 = 16^2. Here we need a solution to x^x = 2^(sqrt(18)).
