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 ...........................................................................

lack electricity and its more savely than electronic microscope because its naturally by using of light
Abdullahi Reply
advantage of electronic microscope is easily and clearly while disadvantage is dangerous because its electronic. advantage of light microscope is savely and naturally by sun while disadvantage is not easily,means its not sharp and not clear

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
