Answer 2

= [(1/2)^3 - (1/2)^4] [(1/2)^3 + (1/2)^4]

= (1/8 - 1/16) (1/8 + 1/16)

= (1/8-1/16)^2

= (1/8)^2 + (1/16)^2 - 2 × 1/8 × 1/16

= 1/64 + 1/256 - 1/64

LCM of (64,256 and 64) = 256

Same the denominator.

1×4/64×4 = 4/256

1×1/256×1 = 1/256

1×4/64×4 = 2/256

= 4/256 + 1/256 - 4/256

= 4+1-4/256

= 5-4/256

= 1/256

= (16)^-2 answer.
