1. a) 2*9+25:1+16*3-6^24:2^22:3^24+13=
= 18+25+48+2^2+13=
=108 >< 100 (F)
b) nu inteleg 2^3x^3?
2)a) (5*111)^3 - 5^3*111^3= 5^3*111^3-5^3*111^3=0
b) calculam prima paranteza astfel: adunam si scadem 1
1+1+2+2^2+....+2^99-1=
=2+2+2^2+2^3+......2^99-1=
=2^2+2^2+2^3+....+2^99-1=
=2*2^2+2^3+....+2^99-1=
=2^3+2^3+.....2^99-1=
=............
=2^100-1
Parantezele sunt egale, deci impartirea lor da 1
^ inseamna la puterea
* inseamna inmultit
>< inseamna diferit (egal taiat)
