va rog ajutati ma va rog!! dau 50 puncte si coroana!!!!

Answer 1

11.
a)(4+4*3)*[(-3)⁴⁹+3*3²*3⁴⁶+(-2)¹⁴⁵:(-2)⁹⁰+(2⁵)¹¹-5²]=
=(4+12)*(-3⁴⁹+3⁴⁹-2¹⁴⁵:2⁹⁰+2⁵⁵-25)=
=16*(-2⁵⁵+2⁵⁵-25)=
=16*(-25)=-400

b)(-5)³*{396-720:[-7+(6590+51*210):(-2²*5²)]}=
=(-5)³*{396-720:[-7+(6590+10710):(-4*25)]}=
=-125*{396-720:[-7+17300:(-100)]}=
=-125*[396-720:(-7-173)]=
=-125*[396-720:(-180)]=
=-125*(396+4)=
=-125*400=
=-50000

c)(I-2I)²+I7I-I(-5)⁰I+I(-1)¹⁶I-I-11I+4*I-5I=
=(2)²+7-I1I+I1I-11+4*5=
=4+7-1+1-11+20=
=11-11+20=20
