Evaluate using suitable identities34 × 36

1.	Evaluate using suitable identities34 × 36
Answer» 34 × 36 = (30 + 4) (30 + 6) This is in the form. (x + a)(x + b) = x²+ (a + b)x + ab Here x =30, a = 4, b = 6 (30 + 4)(30 + 6) = 30² + (4 + 6)30 + 4 × 6 = 900 + 300 + 24 34 × 36 = 1224

Answer»

34 × 36 = (30 + 4) (30 + 6)

This is in the form.

(x + a)(x + b) = x²+ (a + b)x + ab

Here x =30, a = 4, b = 6

(30 + 4)(30 + 6) = 30² + (4 + 6)30 + 4 × 6

= 900 + 300 + 24

34 × 36 = 1224
