This is invalid. Not because the premise isn't true, the premise is always true. But there's nothing that says when "the triangles are not congruent"

For B, if you multiplied the exponents:$\Huge{(x^5)^{\frac{1}{8}}}=x^{(5\times\frac{1}{8})}=x^{\frac{5}{8}}$

And D, that's what I explained with the hint. Not sure what the third one is yet.

Yeah, I agree with kitty, and I think the first one would also be correct. Since the associative property applies to multiplication, the first option and the fourth option are equivalent.
