a)3-(-3)^i3 -(-3)^ 3-(-3)^ 4= b)(-4)^3-4^3-((-5)^4-5^4)= c)3*(7-(-2)^3)-(1-(2-2^2))= d)3-{9-[18-(-2)^3*(-3)^2]}= bardzo prosiłabym o pomoc z tym zad. obliczenia  z góry dziękuje

a) [latex]3-(-3)^3-(-3)^3-(-3)^4=3+3^3-(-3)^3-(-3)^4=3+3^3+3^3-81=3+27+27-81=57-81=-24[/latex] b) [latex](-4)^3-4^3-((-5)^4-5^4)=(-4)^3-4^3-(5^4-625)=(-4)^3-64-(625-625)=-4^3-64=-64-64=-128[/latex] c) [latex]3(7-(-2)^3)-(1-(2-2^2))=3(7+2^3)-(1-(2-4))=3(7+8)-(1+2)=3*15-(1+2)=3*15-3=45-3=42[/latex] d) [latex]3-(9-[18-(-2)^3*(-3)^2])=3-(9-(18-(-2*2^2*9)))=3-(9-(18-(-8*9)))=3-(9-(18+72))=3-(9-90)=3-(-81)=3+81=84[/latex]
