Answer 1

i. (100 + 3)² = 100² ⁺ 2(100)(3) + 3²
= 10 000 + 600 + 9
= 10 609

ii. (80 + 4)² = 80² ⁺ 2(80)(4) + 4²
= 6 400 + 640 + 16
= 7 056

iii. (150 + 5)² = 150² ⁺ 2(150)(5) + 5²
= 22 500 + 1 500 + 25
= 24 025

Answer 2

$(100 + 3)^{2} = 100^{2} +2*100*3 + 3^{2}\\(100 + 3)^{2} = 10000 +600 + 9\\(100 + 3)^{2} = 10609\\\\(80 + 4)^{2} = 80^{2} +2*80*4 + 4^{2}\\(80 + 4)^{2} = 6400 +640 + 16\\(80 + 4)^{2} = 7056\\\\(150 + 5)^{2} = 150^{2} +2*150*5 + 5^{2}\\(150 + 5)^{2} = 22500 +1500 + 25\\(150 + 5)^{2} = 24025$
