Bonjour
Explications étape par étape:
[tex]c = 3 \times {5}^{2} + 4 \\ = 3 \times 25 + 4 \\ = 75 + 4 \\ c = 79 \\ d = {(3 \times 5)}^{2} + 4 \\ = {15}^{2} + 4 \\ = 225 + 4 \\ d = 229 \\ e = 3 \times ( {5}^{2} + 4) \\ = 3 \times (25 + 4) \\ = 3 \times 29 \\ e = 87 \\ f = 3 \times {(4 + 5)}^{2} \\ = 3 \times {9}^{2} \\ = 3 \times 81 \\ f = 243[/tex]
