Efectueaza calculele: a)10+4×3^2-7×5-(3+2^3)
b)(10^2-7^2+5^4)×223^0+1^1500)


Răspuns :

a)10+4×3^2-7×5-(3+2^3)=
=
10+4×9-35-(3+8)=
=10+1-11=
=11-11=0

b)(10^2-7^2+5^4)×223^0+1^1500=
=
(100-49+625)×1+1 =
=676+1 =677

fac si varianta cu paranteza
(10^2-7^2+5^4)×(223^0+1^1500=
=
(100-49+625)×(1+1) =
=676×2 =1352
