Math Problem Statement
(5log10)2 – (5log2)2/5log√20 =
Solution
Let's simplify the given expression step by step.
The expression is:
Step 1: Simplify
Since (logarithm base 10 of 10 is 1):
So,
Step 2: Simplify
We can't simplify to a simple value, so we leave it as . Now square it:
Step 3: Simplify the denominator
Using logarithmic properties :
Now we express as , since and :
So,
Step 4: Substitute and simplify the entire expression
The expression now becomes:
Now, you can simplify further from here.
