Question

Comparati numerele: x=3^2004+ 3^2004+ 3^2004 si y=3^2005 ​

Answer 1

x=3²⁰⁰⁴+3²⁰⁰⁴+3²⁰⁰⁴=3²⁰⁰⁴(1+1+1)=3²⁰⁰⁴3=3²⁰⁰⁵.

y=3²⁰⁰⁵.

comparand cele doua numere constatam evident ca sunt egale, x=y.

Answer 2

Răspuns:

x=3^2004+ 3^2004+ 3^2004

x=3^2004·(1+1+1)

x=3^2004·3^1

x=3^(2004+1)

x=3^2005

y=3^2005 ​

x=y
