Need answer for 8th question

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 =
Hope this helps :)
5² means 5 × 5
12² means 12 × 12
5² = 5 × 5 = 25
12² = 12 × 12 = 144
Now add 144 and 25:
144 + 25 = 169
