a) 3¹²:3¹⁰+(3•5)¹⁰:15⁹-2011⁰•1²⁰¹¹= 3¹²‐¹⁰+15¹⁰:15⁹-1•1= 3²+15¹⁰‐⁹-1= 9+15¹-1= 9+15-1=24-1=23
b) 4¹³:8⁶+7³-5²•[625:5⁴+16:(7•3²-55)]=
4¹³:8⁶+343-25•[625:625+16:(7•9-55)]=
4¹³:8⁶+343-25•[1+16:(63-55)]=
4¹³:8⁶+343-25•(1+16:8)=
4¹³:8⁶+343-25•(1+2)=4¹³:8⁶+343-25•3= 4¹³:8⁶+343-75
(si cred ca se face asa..nu sunt sigura)
4¹³:4⁶•2+268=4¹³‐⁶•2+268=4⁷•2+268= 16.384•2+268=
32.768+268=33.036
c) 18•[1+3⁷•3⁵³+7⁸⁴:7¹⁴+(5⁴)²⁰]:(13⁰+3⁶⁰+7⁷⁰+5⁸⁰)=
18•(1+3⁷+⁵³+7⁸⁴‐¹⁴+5⁴°²⁰):(13⁰+3⁶⁰+7⁷⁰+5⁸⁰)=
18•(1+3⁶⁰+7⁷⁰+5⁸⁰):(13⁰+3⁶⁰+7⁷⁰+5⁸⁰)=
18•1:13⁰=18:13⁰=18:1=18
