Uita-te acum ca am mai bagat o poza.

Answer 2

a). 10+4x3^2-7x5-(3+2^3)=10+4x9-35-(3+8)=10+54-35-24=5

b). 2017-{[42-(5^2x14-85x4)x2]x3+2^6}=2017-{[42-(25x14-340)x2]x3+64}=

2017-{[42-(350-340)x2]x3+64}=2017-[(42-10x2)x3+64]=2017-[(22x3)+64]=

2017-(66+64)=2017-130=1887

c). (10^2-7^2+5^4)x(223^0+1^1300)=(100-49+625)x(1+1)=676x2=1352
