should be correct
Answer:
1. 
2. 
3. 
Step-by-step explanation:

Write in exponential form
Using the law of logarithm which says if
then

By comparison;
A = 16; b = 2 and x = 4
The expression
becomes


Write in exponential form
Applying the same law as used in (1) above;
A = 2; b = 16 and 
The expression
becomes

Write in logarithm form
Using the law of logarithm which says if
then

By comparison;
b = 2; x = z and A = y
The expression
becomes
