(6xy^3)^-3
First, multiply-through the 3.
(18xy^9)^-
Then the -.
(-18xy^9)
Then the ^.
(-18xy^²9)
Then the parentheses cancel each other out.
-18xy^²9
Expand the ^, and rearrange.
^-8xy^19.
Rotate the 8, and move the - down a bit.
^_∞xy^19
Set the x & y aside for a bit, and split the ∞ apart.
Rearrange, and you arrive at your solution:
I dunno LOL
^o_o^
Edit: Ah, now I see the second part. I completely missed the:
_______
(8x^-4y^3)
, having mistook it for a signature, and thus not related to the post. Derp.
I still prefer my solution though. And yes, 'tis not an equation if there's no equals sign.
