(2k + 4)^2 =

= (2k + 4) × (2k + 4)

= 2k × 2k + 2k × 4 + 4 × 2k + 4 × 4

= 4k^2 + 8k + 8k + 16

Hasil = 4k^2 + 16k + 16

(4t - 3)^5 =

= (4t - 3)^3+2

= (4t - 3)^3 × (4t - 3)^2

= (64t^3 - 144t^2 + 108t - 27) × (16t^2 - 24t + 9)

= 1024t^5 - 1536t^4 + 576t^3 - 2304t^4 + 3456t^3 - 1296t^2 + 1728t^3 - 2592t^2 + 972t - 432t^2 + 648t - 243

Hasil = 1024t^5 - 3840t^4 + 5760t^3 - 4320t^2 + 1620t - 243
