Aratati ca m=|1-4|+(6-11)²+ 3
()[tex]( \frac{1}{x^{2} } + \frac{1}{x} ) * \frac{x^{3}}{x+1} [/tex] unde e(x)apartine R
Multumessc anticipat !!!


Răspuns :

m = /-3/ + ( -5 )^2 + 3 => m = 3 + 25 + 3 => m = 31 ;
( 1 / x^2 + 1 / x ) = ( 1 / x^2 + x / x^2 ) = ( x + 1 ) / x^2 ;
atunci,  = [ ( x + 1 ) / x^2 ] * [ x^3 / ( x + 1 ) ] = x ;

Bafta !
