Question

ex 6 (cel cu forma ireductibila) va rog dau coroana!!!!!

Answer 1

Răspuns:

= $\frac{x}{y}$  notez asa sa fie mai simplu

x= 9⁹-8*9⁸-8*9⁷= (3²)⁹-2*4*(3²)⁸-2*4*(3²)⁷=3¹⁸-2*4*3¹⁶- 2*4*3¹⁴= 3¹⁴( 3⁴- 8*3²-8)= 3¹⁴*(9*9-8*9-8)=3¹⁴*(81-72-8)=3¹⁴*1= 3¹⁴

y= 3¹⁸- 2*3¹⁷-2*3¹⁶= 3¹⁶(3²-2*3¹- 2)=3¹⁶(9-6-2)= 3¹⁶*1= 3¹⁶=3¹⁴*3²=3¹⁴*9

$\frac{x}{y}$= $\frac{3^{14} }{3^{14}*9 }$= $\frac{1}{9}$
