Question

Cặp (x,y) thỏa mãn:

(x-3)²⁰¹²+(3y-12)²⁰¹⁴ <=0

Answer 1

Ta có:

\(\left(x-3\right)^{2012}\)>=0

\(^{\left(3y-12\right)^{2014}}\)>=0

Mà \(\left(x-3\right)^{2012}\)+\(^{\left(3y-12\right)^{2014}}\)<=0

=>\(\left(x-3\right)^{2012}\)=0 =>X-3=0 =>x=3

=>\(^{\left(3y-12\right)^{2014}}\)=0 =>3y-12=0 =>3y=12 =>y=4

Vậy x=3;y=4
