Question

Se considera numerele : x = 12 ×8 +8 ×3+6×5+6× 12 la puterea 0 si y =12×8-8×3-6×5-6.Calculeaza suma dintre diferenta si produsul numerelor x și y.

Answer 1

x = 12 x 8 + 8 x 3 + 6 x 5 + 6 x 12⁰

x = 96 + 24 + 30 + 6 x 1

x = 96 + 24 + 30 + 6

x = 120 + 30 + 6

x = 150 + 6

x = 156

---------------------------------------

y = 12 x 8 - 8 x 3 - 6 x 5 - 6

y = 96 - 24 - 30 - 6

y = 72 - 30 - 6

y = 42 - 6

y = 36

-----------------------------------------

⇒ ( 156 - 36 ) + ( 156 x 36 )  =

⇒ 120 + 5616

⇒ 5736

Answer 2

x =  12 × 8 + 8 × 3 + 6 × 5 + 6 × 12⁰

x = 96 + 24 + 30 + 6

x = 156

________________________

y = 12 × 8 - 8 × 3 - 6 × 5 - 6

y = 96 - 24 - 30 - 6

y = 36

____________________________

( 156 - 36 ) + ( 156 × 36 ) = 120 + 5 616 = 5 736 → suma dintre diferenta si produsul numerelor x si y
