I don't know how to show that:
2/log underscore9 A-1/log underscore3 A = 3/log underscore3 A
2/log underscore9 A-1/log underscore3 A = 3/log underscore3 A
see post number 8 by JamesRhow you got 1/2log_3A
A logarithm is a mathematical function that is the inverse of the exponential function. It is used to solve equations involving exponential expressions and is commonly denoted as log(x).
To solve a logarithmic equation, you can use the properties of logarithms, such as the product, quotient, and power rules. You can also use the change of base formula to rewrite the equation in a form that is easier to solve.
Yes, logarithms can be negative. However, the argument of the logarithm (the number inside the parentheses) must be positive. If the argument is negative, the logarithm is undefined.
Logarithms are used to solve equations involving exponential expressions and to simplify complex calculations. They are also used in various fields such as finance, science, and engineering to express large numbers in a more manageable form.
The relationship between logarithms and exponents is that they are inverse functions of each other. This means that if you take the logarithm of a number, you can find the exponent that was used to get that number. Similarly, if you raise a number to a certain exponent, you can find the logarithm of that number.
