Sagot :
Alors 8-(3x3)+5
-10-92 = 8-9+5-10-92 = -98
B. (-8)x(-8)+3(7x7) -(2x2x2)+ (7-9) = 64+(3x49) -8-2 = 64+147-8-2 = 201
C. 4-(5x5)+10-((-2)x(-2)x-(2)) = 4-25+10-(4x(-2)) = 4-25+10-(-8) = 4-25+10+8 = -3
D. ((-2)x(-2)x(-2))-(2x2)-3((2x2x2)-(3x3)) = (4x(-2))-4-(3x8)-9 = -8-4-24-9 = -45
Voilà, j'espère t'avoir aidé.
À=8+9+5-10-92=22-102=-80
B=64+3x7au carre-8-2=64+3x49-10=64+147-10=201
C=4+25+10-(-8)=4+25+10+8=47
D=(-8)+4-3x(8+9)=-4-3x17=-4-51=-55
