[(13!)^16 - (13!)^8 ] / [ (13!)^8 + (13!)^4 ]/(13!)^4
=>[(13!)^12 - (13!)^4 ]/ [ (13!)^8 + (13!)^4 ]
=> ((13!)^8 - 1)/((13!)^4 + 1)
=>(13!)^4 - 1
so units =10-1=9

Two functions, f and g, are such that 4*{g(x)}2 β 2f(x)f(βx) = {f(x)}^2 + {f(βx)}^2. If g(4) = 20, what is the value of g(β4)?

4g(x)^2 = ( f(x) + f(-x) ) ^2
so g(-4) = 20 ?
