2nd option) 1/27^7 is equivalent to 27^-4(27^5•27^2)-1

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
