1. Skryf in logaritmiese vorm :
1.1 y = 2x
1.2 y = 5x
1.3 49 = 72
1.4 81 = 34
1.5 y = (1/2)x
1.6 y = (1/7)x
1. Write in log form :
1.1 y = 2x
1.2 y = 5x
1.3 49 = 72
1.4 81 = 34
1.5 y = (1/2)x
1.6 y = (1/7)x
2. Skryf in eksponensiale vorm :
2.1 y = logb x
2.2 a = logb c
2.3 y = log3 x
2.4 y = log(1/2) x
2.5 log3 9 = 2
2.6 log(1/2) 8 = −3
2.7 log 100 = 2
2.8 log x = y
2. Write in exponential form :
2.1 y = logb x
2.2 a = logb c
2.3 y = log3 x
2.4 y = log(1/2) x
2.5 log3 9 = 2
2.6 log(1/2) 8 = −3
2.7 log 100 = 2
2.8 log x = y
3. Los op vir x en gee u antwoord korrek tot twee
desimale syfers :
3.1 2x = 5
3.2 4x = 18
3.5 3.5x = 10
3.6 7x = 114.6x
3. Solve for x and give your answer correct to two
decimal digits :
3.3 2x − 2 = 8
3.4 7x + 1 = 13
3.7 3x.9 x + 1 = 36
3.8 26.(1,125)x = 312
4. As log 2 = a; log 3 = b en log 5 = c, skryf
die volgende i.t.v. a,b en c :
4.1 log 6
4.2 log 25
4.5 log 12
4.6 log 2,5
4.9 log 7,5
4.10 log 36
4.13 log 3 2
4.14 log 2 5
4. If log 2 = a; log 3 = b and log 5 = c, write
the following in terms of a,b and c :
4.3 log 15
4.4 log 18
4.7 log 1,2
4.8 log 45
4.11 log 40
4.12 log 375
4.15 log 5 6
4.16 log 3 2,5
