efectueaza apoi determina x daca x=2,(3)+{(-2/3) la puterea -2} totul la puterea 1002•(-4/9) la puterea 1001

Răspuns :

 x=2,(3)+{(-2/3)⁻²}¹⁰⁰²•(-4/9)¹⁰⁰¹
2,3=(23-2)/9=21/9=7/3

 x=2,(3)+{(-2/3)⁻²}¹⁰⁰²•(-4/9)¹⁰⁰¹=
=7/3+{(-2/3)⁻²}¹⁰⁰²•[-(2/3)²⁰⁰²
=7/3+(-3/2)²⁰⁰⁴•[-(2/3)²⁰⁰²
=7/3+(3/2)²⁰⁰⁴•[-(2/3)²⁰⁰²
=7/3-3²/2²=7/3-9/4=(28-27)/12=1/12
