Question

what is the value of $\log_{16}4$?
-1
$\frac{1}{4}$
$\frac{1}{2}$
4

Explanation:

It seems the question is not clear as it is written as "What is the value of \(10_{10}-5\)?" which might have some typo. Assuming you mean \(10 - 5\):

Step1: Perform subtraction

\(10-5 = 5\)
But if it is a non - standard notation and you mean something else, the interpretation will change. If it is a limit - related question and the notation is not correct as presented. Assuming it is a simple arithmetic subtraction:

Answer:

5

If the question was meant to be something like a logarithm or some other operation and the notation was mis - written, more clarification is needed.
