Question

Vă rog am nevoie de ajutor!exercițiul 16 doar de el am nevoie!!!!

Answer 1

a)

7x = y8 ⇒x = 8, y = 7 ⇒ 78 = 78

b)  

xx = y2 ⇒x = 2, y = 2

c)

5y7< 50x ⇒y=0 si x=8 si 9

508  si 509

d)

2xy> 289 ⇒x = 9 si y = {0,1, 2,3,4,5,6,7,8}

291, 292, 293, 294, 295, 296, 297, 298}

e)

72x398 < 724y28 ⇒

x= 4, si y= {4, 5, 6,7, 8, 9}

x= 3 si  y ={0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

x = 2 si  y = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

x = 1 si  y ={0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

x = 0 si  y ={0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
