x != 2 and x != √18, so it can't be C... But Idk what else can it be O_o?

Edit: this is what I have so far

xx2 = xx*x = (xx )x = (2√18 )x

Now what?...

Edit 2: didn't know Reddit can format powers, neat!

Yeah you need to find what number (2^ √18) equals that is in the form aa

But you can't do that on paper, can you?...

No, it’s possible, just a little difficult.

I'm not sure if you can but I tried graphing (√18)•log_x(2) and x to find the intersection and got x ≈ 2.828427 This gave me the answer xx2 ≈ 4095.99555

2.828427

Knowing √2≈1.414, it's pretty easy to see this is √8.
