May I know how to calculate this question without a calculator? The final answer of this question is 3 but I really have no idea how to work on it to get the final answer.

Is it something to do with the changing base formula? I have tried using the changing base formula, hoping through this I could simplify it but it went even complicated. Then I was stuck, don't know how to solve it...Jdtbtb_sp said:May I know how to calculate this question without a calculator?

log_2(log_3(65)) + 3*log_5(log_5(9)) - Wolfram|Alpha

A logarithm is the inverse operation of exponentiation. It is a mathematical function that helps us solve for the exponent in an exponential equation. For example, in the equation 2^x = 8, the logarithm (base 2) of 8 is 3, since 2^3 = 8.
To calculate a logarithm, you need to know the base and the number you are taking the logarithm of. For example, if you want to calculate log base 10 of 100, you would write it as log_{10}100. This is read as "log base 10 of 100." The answer would be 2, since 10^2 = 100.
Natural logarithms, written as ln(x), use the base e (Euler's number) and are often used in calculus and other advanced mathematical concepts. Common logarithms, written as log(x), use the base 10 and are more commonly used in everyday calculations.
Logarithms are used in a variety of fields, including finance, science, and engineering. They are commonly used to measure the intensity of earthquakes (Richter scale), the loudness of sounds (decibels), and the acidity of substances (pH scale). They are also used in compound interest calculations and to solve exponential growth and decay problems.
Yes, there are several rules and properties of logarithms that can be used to simplify calculations. Some of the most common ones include the product rule, quotient rule, and power rule. These rules can help us solve complex logarithmic equations more easily.
