Va roog din suflet dau coronita + cel mai bun raspuns !!! Si 30 pcte!_

Answer 1

a) (16·12¹⁰⁻⁴·12¹⁰):12¹¹=
    =(16·12⁶):12¹¹=
     =16·12¹¹⁻⁶=
     =16·12⁵=
     =192⁵

b)10³·85-10³·61-3000=
   =1000·85-1000·61-3000=
   =85000-61000-3000=
   =24000-3000=
   =21000

c)15²-(14·15+15):15²=
   =15²-215:15²=
   =10:15²=
   =0,0(4)

d)5¹¹-(6·5¹⁰-2·5¹⁰)=
  =5¹¹-(30-10)¹⁰=
  =5¹¹-20¹⁰=
  =(20-5)¹¹⁻¹⁰=
  =15¹=
  =15
