Answer: Explanation below.
Step-by-step explanation:
First of all you need to know how to convert a logarithm into an exponential expression. The property is:

This is the same as: 
Example 1:

We are trying to find what to raise 9 to, in order to get a result of 9.

When you have same bases, you equal exponents.

Therefore; 
Example 2:


In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as:
which is 2*2*2*2*2
Rewriting this example we have;

Since we have the same base, we equal exponents.

Therefore; 
Example 3:


729 can have a base of 3 if expressed as: 


A) 1+7n
b) 12+4n
Where in both cases n starts from 0
Answer:
Diagonal is 36.06 inches
Step-by-step explanation:
Using Pathogoras' Theorem:
√(20²+30²) = 36.0555in
≈ 36.06in
