Answer:
a) 5/9
b) 7
c) 5
Step-by-step explanation:
For a)
One of the rules for logs is that if there is a logarithm subtracted by a logarithm and they have the same base, it is the same as the log with the same base and the arguments are divided:
= 
so for this problem, they have the same base, so you can use this rule:

For b)
This is very similar, except instead of dividing the arguments, you want to multiply them.
So this is kind of saying "8 multiplied by x equals 56"
which is 7
For c)
If the argument has its own exponent, it can be brought to the front of the log like so:

This one is a bit tricky because you have to actually set 32 into an exponent form first.

Then we can bring that 5 in front of the logarithm

So the answer is 5
