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"

And D, that's what I explained with the hint. Not sure what the third one is yet. 2 months ago

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. 2 months ago

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.
