Math help?no idea wat to do?

Question

i have this math problem that is just about the most confusing thing ive ever SEEN.

im gonna try to write it out if i can but its sort of hard so if u can help me out with this one please do.ill appreciate it so muchhh

here it goes:

Simplify:

x(1-2x)^-1(then theres a subscript to the power(2))+(1-2x)^-2(subscript to the power(2))

anyone have an idea of what to do with the subscripts??????

thx

Answer 1

I could understand the subscripts being right next to a variable to denote a different variable (e.g., x_1, x_2, x_3).  Or in a logarithm.  But that's weird.  The only thing I can think of is the subscript meaning "base 2" (binary).  But then that wouldn't make sense here.
