Răspuns:

Explicație pas cu pas:

y = 5·(3²⁰⁰²-3²⁰⁰¹-9¹⁰⁰⁰) = 5·(3²·3²⁰⁰⁰-3·3²⁰⁰⁰ - 3²⁰⁰⁰) = 5·3²⁰⁰⁰ ·(9-3-1) = 5²·3²⁰⁰⁰

(4³¹+6·32¹²-5·16¹⁵):(8²¹-5·8²⁰) - 1 = [(2²)³¹+6·(2⁵)¹²-5·(2⁴)¹⁵]:[(2³)²¹-5·(2³)²⁰] - 1 =

= [2⁶²+6·2⁶⁰-5·2⁶⁰] : [2⁶²-5·2⁶⁰]-1 = [2⁶⁰·(4+6-5)] : [2⁶⁰·(4-5)] -1 =

(2⁶⁰·5) :(2⁶⁰·(-1) -1 = 5:(-1)-1 = -5-1 = -6
