In summary, to solve the equation 6^log x=1/36, you can take the log of both sides and use the rules of logs to solve for log(x). If you want to take a shortcut, 1/36 can be rewritten as 6^-2. However, the answer is not -2, but rather 0.01. To solve for x, you will need to know the base of the logarithms, which should be stated in the problem or textbook. If the base is 10, then log(x) = -2, and x = 0.01.

How do u solve this? I know the 1/36 is the exponent. Usually the logs that u normally do is not in an exponent like this. The answer is 0.01. How did they get that?

Take the log of both sides. Use rules of logs and solve for log(x). If you want to take a shortcut, 1/36=6^(-2), right?

I thought the ans was -2 since 6^-2 = 1/36

But the ans is 0.01. So that means it is not...

log(x)=(-2). x isn't -2. You are supposed to solve for x. What's the base of your logarithms?

It should be stated in the problems or your book what the base is. Suppose it is 10. Then if log(x)=(-2), what is x?
 

What is a logarithm?

A logarithm is a mathematical function that determines the power to which a base number must be raised to equal a given number. It is the inverse of exponentiation.

How do you solve logarithmic equations?

To solve a logarithmic equation, you must use the properties of logarithms to rewrite the equation into a simpler form. Then, you can solve for the variable by isolating it on one side of the equation and using the inverse operation of logarithms, which is exponentiation.

What are the properties of logarithms?

The three main properties of logarithms are the product rule, quotient rule, and power rule. The product rule states that the log of the product of two numbers is equal to the sum of the logs of the individual numbers. The quotient rule states that the log of the quotient of two numbers is equal to the difference of the logs of the individual numbers. The power rule states that the log of a number raised to a power is equal to the product of the power and the log of the number.

What is the natural logarithm?

The natural logarithm, denoted as ln, is a logarithm with a base of e, where e is the mathematical constant approximately equal to 2.71828. It is commonly used in calculus and other areas of mathematics.

How is logarithm used in real life?

Logarithms are used in many real-life applications, such as calculating earthquake intensity, measuring sound levels, and analyzing financial data. They are also commonly used in science and engineering to express large or small quantities in a more manageable form.
