Question

Se considera numerele naturale:
a=2+2 produs[2+2 produs(2+2 produs 2)]
b=824:8-(700:14 +720:16)
c=3la puterea55:3la puterea53+(8la puterea15:4la puterea20-2la putera108:2la puterea105 produs 3)la puterea 20:4 la puterea30
a)Calculati si comparati numerele a,bsic.
b)Aflati numerele naturale x pentru care x + 1 linie (a-b-c)

Answer 1

Cred ca LINIE inseamna IL DIVIDA PE..... a=30 b=8 a^b^c de la cel mai mare la c=cel mai mic.atat stiu. cel mai mic. Sper ca oricum te-am ajutat! :(

Answer 2

a=2+2x[2+2x(2+2x2)]=2+2x[2+2x6]=2+2x14=2+28=30
a=30
b=824:8-(700:14 +720:16)=103-(50+45)=103-95=8
b=8
c=3⁵⁵:3⁵³+(8¹⁵:4²⁰-2¹⁰⁸:2¹⁰⁵x3)²⁰:4 ³⁰=3⁵⁵⁻⁵³+[(2³)¹⁵:(2²)²⁰-2¹⁰⁸⁻¹⁰⁵x3)²⁰:(2²)³⁰=
   3²+(2⁴⁵:2⁴⁰-2³x3)²⁰:2⁶⁰=9+(2⁴⁵⁻⁴⁰-8x3)²⁰:2⁶⁰=9+(2⁵-24)²⁰:2⁶⁰=
   9+(32-24)²⁰:2⁶⁰=9+8²⁰:2⁶⁰=9+(2³)²⁰:2⁶⁰=9+2⁶⁰:2⁶⁰=9+2⁶⁰⁻⁶⁰=
   9+2°=9+1=10
c=10
a)  b<c<a
8<10<30
b)Aflati numerele naturale x pentru care x + 1 linie (a-b-c)
a-b-c=30-8-10=12
x+1I12
D12={1,2,3,4,6,12}
x+1=1⇒x=1-1⇒x=0
x+1=2⇒x=2-1⇒x=1
x+1=3⇒x=2
x+1=4⇒x=3
x+1=6⇒x=5
x+1=12⇒x=11
x∈{0,1,2,3,5,11}
