Answer 1

The solution is 628

Explanation:

12²+22²

= (12×12)+(22×22)

= 144+484

= 628

Answer 2

1156

Explanation:

We know that,

( a + b ) ² = a² + 2ab + b²

We can follow the same method to find the value of this.

12² + 22²

( 12 + 22 ) ²

12² + 2 × 12 × 22 + 22²

144 + 24 × 22 + 484

144 + 528 + 484

672 + 484

1156
