Question

Va rog cat mai repede si rezolvarea completa!

Answer 1

[tex]\frac{3 \sqrt{7} x^{2} y^{2} - \sqrt{7} x y^{2} +2 \sqrt{7} x^{2} y}{- \sqrt{7} xy} \\ \frac{ \sqrt{7} xy*(3xy-y+2x) }{- \sqrt{7} xy} \\ -(3xy-y+2x) \\ -3xy+y+2x[/tex]

Answer 2

A) 3√7x²y²:(-√7xy)= -3y
     -√7xy²: (-√7xy)= +y
     +2√7x²y:(-√7xy)= -2x
   -3y+y-2x= -2y-2x
B) 10x⁴y³:5x²y²= 2x²y
     15x³y⁴:5x²y²= 3xy²
      5x³y³:5x²y²=xy
2x²y-3xy²-xy
SPER CA TE-AM AJUTAT!
