= 13 - 16 x (5 - 8)² = 13 - 16 x (-3)² = 13 - 16 x 9 = 13 - 144 = 131

Bonjour,

[tex]A = 13 - 2^4(5-2 \times 4)^2\\A = 13 - 2^4(5-8)^2\\A = 13-2^4\times (-3)^2\\A = 13-2^4\times 9\\A = 13 - 16\times 9\\A = 13-144\\A = -131\\\\B= 4 \times (-5)^2 + 2\times 10^3\\B = 4 \times 25 + 2 \times 10^3\\B = 4 \times 25 + 2\times 1000\\B = 100 + 2000\\B=2100\\[/tex]
