LOGARITHMIC FORM TO EXPONENTIAL FORM WORKSHEET

Change the following from logarithmic form to exponential form :

1)  log 464   =  3

2)  log162  =  1/4

3)  log5(1/25)  =  -2

4)  log100.1 =  -1

5)  log6216 =  3

6)  log93 =  1/2

7)  log51  =  0

8)  log√3 9  =  4

9)  log64 (1/8)  =  -1/2

10)  log0.5 8  =  -3

Solve for x :

11)  log2x  =  1/2

12)  log1/5x  =  3

Answers : 

1)  64  =  43

 2)  =  161/4

3)  (1/25)  =  5-2

4)  0.1  =  10-1

5)  216  =  63

6)  3  =  9(1/2)

7)  1  =  50

8)  9  =  (√3)4

9)  (1/8)  =  64(-1/2)

10)  8  =  0.5-3

11)

log2x  =  1/2

Convert to exponential form. 

x  =  21/2

x  =  √2

12)

log1/5x  =  3

Convert to exponential form. 

x  =  (1/5)3

x  =  13/53

x  =  1/125
