Question

604×609 evaluate using suitable identities

Answer 1

Answer:

Evaluate using the following steps as follows:

604 × 609 = (600+4) (600+9)

Using (x+a) (x+b) = x^2 +(a+b) x + (a×b)

(600+4) (600+9) = (600 × 600) + (4+9) (600) +(4×9)

360,000 + 13(600) +36

360,000 + 7,800 + 36

367,836

Answer 2

Answer:3,67,836

Step-by-step explanation:

(600+4)(600+9)

(x+a)(x+b)=>x²+(a+b)x+ab

(600)²+(4+9)600+4*9

360000+7800+36

3,67,836
