Answer 1

Răspuns:

(3^2 + 4^2) : 5 = (9 + 16) : 5 = 25 : 5 = 5

________

(27 + 3 · 4^2) : 15 = (27 + 3 · 16) : 15 = (27 + 48) : 15 = 75 : 15 = 5

________

(12^2 + 5^2) : 13 = (144 + 25) : 13 = 169 : 13 = 13

Answer 2

Răspuns:

Explicație pas cu pas:

(3² + 4²) : 5 = (9 + 16) : 5 = 25 : 5 = 5

(27 + 3 × 4²) : 15 = (27 + 3 × 16) : 15 = (27 + 48) : 15 = 75 : 15 = 5

(12² + 5²) : 13 = (144 + 25) : 13 = 169 : 13 = 13
