Answer 2

Answer:

256 wholepower 6-1

Step-by-step explanation:

(2x-1)(2x+1)(4x square+1)(16x power 4+1)

(a+b)(a-b)=a square- b square

a=2x

b=1

(4x) square-(1)square

(4xsquare)-(1 square)(4x square)+(1 square)

(4xsquare)square-(1 square) square

(16x wholepower 4)-(1)

{(16x wholepower 4)-(1)}-{(16x wholepower 4)+(1)}

=256 wholepower 6-1
