Answer 1

Primeiro resolve o parêntese.
(5-3)^2 = 2^2 = 4.
(6-0)^2 = 6^2 = 36.
(3-(-1))^2 = 4^2 = 16
(4-4)^2 = 0^2 = 0

5^2 - 3^2 = 25 - 9 = 16
6^2 - 0^2 = 36
3^2 - (-1)^2 = 9 - 1 = 8
4^2 - 4^2 = 16 - 16 = 0.

Answer 2

$(a - b) {}^{2} \\ (5 - 3) {}^{2} = 4 \\ {(6 - 0)}^{2} = 36 \\ {(3 + 1)}^{2} = 16 \\ {(4 - 4)}^{2} = 0$
${a}^{2} - {b}^{2} \\ {5}^{2} - {3}^{2} = 25 - 9 = 16 \\ {6}^{2} - {0}^{2} = 36 \\ {3}^{2} - { (- 1)}^{2} = 9 - 1 = 8 \\ {4}^{2} - {4}^{2} = 0$
