The answer is 169

5² means 5 × 5

12² means 12 × 12

5² = 5 × 5 = 25

12² = 12 × 12 = 144

144 + 25 = 169

Answer 2

169

In this problem, we need to use squaring method.

5² means 5 × 5

5² = 25

12² means 12 × 12

12² = 144

So, simplify these statements:

5² × 12²

25 + 12² (Simplify 5², which means 5 × 5)

25 + 144 (Simplify 12², which means 12 × 12)

We get the answer:

25 + 144 =
