Getallestelsel

(natuurlike- en telgetalle)

Module 1

Verskillende soorte getalle

KLASOPDRAG

  • Kom ontdek stap vir stap meer oor die getallestelsel....

1. Algemeen: Verskillende soorte getalle

Gee voorbeelde van elk van die volgende getalle:

  • Natuurlike getalle N = {..................................................}
  • Telgetalle N 0 = {..................................................}
  • Heelgetalle Z+ = {..................................................}

Z- = {..................................................}

  • Rasionale getalle Q = {..................................................}
  • Irrasionale getalle Q’ = {..................................................}
  • Reële getalle R = {..................................................}

2. Natuurlike getalle

Priemgetalle ={..................................................} Saamgestelde getalle ={..................................................}
Definisie: .........................................................................................…………..................................................…………..................................................………….......... Definisie: .................................................................…………..........................................................................…………..................................................…………..........

Priemgetalle + Saamgestelde getalle = Natuurlike getalle

3. Deelbaarheidsreëls

Kies elke keer ‘n getal wat deelbaar is deur die gegewe deler en probeer ‘n reël by elke geval aflei.

Getal Deler Deelbaarheidsreël
3.1 2
3.2 3
3.3 4
3.4 5
3.5 6
3.6 8
3.7 9
3.8 10
3.9 11

4. Bepaal deur watter getalle (3.1 - 3.9) 61 226 deelbaar is, en gee ‘n rede by elk.

5. Wat verstaan jy onder elk van die volgende terme:

5.1 Veelvoud:

5.2 Faktor:

5.3 Priemgetal:

5.4 Priemfaktor:

5.5 Ewe getalle en onewe getalle:

  • Hoe bepaal jy die faktore van ‘n getal? Kyk ‘n bietjie.....bv. F 24 = {1; 2; 3; 4; 6; 8; 12; 24} 1 x 24; 2 x 12; 3 x 8; 4 x 6

6. Bepaal die faktore van 48.

7. Skryf al die veelvoude van 6 tussen 23 en 56 neer.

8. Bepaal die priemgetalle tussen 17 en 78.

9 Bepaal alle onewe saamgestelde getalle tussen 16 en 50.

10 Skryf al die faktore van 50, wat priemgetalle is, neer.

11. Skryf al die faktore van 50, wat saamgestelde getalle is, neer.

12. Verklaar: Kubusgetalle. Skryf die eerste ses kubusgetalle neer.

13. Verklaar: Vierkantgetalle. Skryf die eerste tien vierkantgetalle neer.

HUISWERKOPDRAG

1. Gee die definisie van elk van die volgende:

1.1 Rasionale getal:

1.2 Priemgetal:

1.3 Saamgestelde getalle:

1.4 Priemfaktore:

2. Kies uit {0; 1; 2; 3; 4; ... ; 36} en skryf neer:

2.1 Eerste twee saamgestelde getalle

2.2 Onewe getalle wat nie priemgetalle is nie

2.3 Veelvoude van 6

2.4 Faktore van 12

2.5 Priemfaktore van 12

2.6 Faktore van 36

3. Watter van die volgende getalle - 9 / 3 ; 7 / 0 ; 0; 3; -9; 16; 2 1 / 3 is:

3.1 Telgetalle?

3.2 Rasionale getalle?

3.3 Nie-reële getalle?

4. Tabelleer die volgende:

4.1 Natuurlike getalle<5 ...........................................................................

4.2 Priemgetalle<10 ...........................................................................

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

What is different between quantity demand and demand?
Shukri Reply
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

Economic growth as an increase in the production and consumption of goods and services within an economy.but Economic development as a broader concept that encompasses not only economic growth but also social & human well being.

it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
