Using the identity (a + b)2 = (a2 + 2ab + b2), evaluate:(i) (609)2 (ii

1.	Using the identity (a + b)2 = (a2 + 2ab + b2), evaluate:(i) (609)2 (ii) (725)2
Answer» Answer: Here's UR answer... (i) (609)^2 = (600+9)^2 = (600)^2 + 2×600×9 + (9)^2 = 3600 + 10800 + 81 = 3681+10800 = 14481 (ANS.) (ii) (725)^2 = (700+25) = (700)^2 + 2×700×25 + (25)^2 = 4900 + 35000 + 625 = 5525 + 35000 = 40525 HOPE IT HELPS... PLEASE MARK ME BRAINLIEST!

Answer: Here's UR answer...

(i) (609)^2 = (600+9)^2

= (600)^2 + 2×600×9 + (9)^2

= 3600 + 10800 + 81

= 3681+10800

= 14481 (ANS.)

(ii) (725)^2 = (700+25)

= (700)^2 + 2×700×25 + (25)^2

= 4900 + 35000 + 625

= 5525 + 35000

= 40525
