How to use TI-73 to find the value of logarithm?

The TI-73 is a powerful graphing calculator that can be used to perform a wide range of mathematical calculations. One useful application of this calculator is finding the value of logarithms. Logarithms are mathematical operations that require complex calculations, but with the help of a calculator like the TI-73, it becomes a much simpler task. In this article, we will discuss how to use the TI-73 to find the value of logarithm.

Using the TI-73 to Find the Value of Logarithm

To find the value of a logarithm using the TI-73, follow these steps:

Step 1: Access the Logarithm Function

Press the “LOG” key on the TI-73 calculator. This key is usually located near the exponential function key and is labeled with “LOG” or a similar symbol.

Step 2: Enter the Base of the Logarithm

Enter the base of the logarithm using the number keys on the calculator. For example, if you want to find the value of log base 2, enter the number 2 on the calculator.

Step 3: Specify the Argument of the Logarithm

Enter the argument of the logarithm using the number keys on the calculator. The argument is the number for which you want to find the logarithm. For example, if you want to find the logarithm of 8, enter the number 8 on the calculator.

Step 4: Calculate the Logarithm

Press the “=” key on the calculator to calculate the logarithm. The calculator will display the value of the logarithm on the screen.

Example:

Let’s say you want to find the value of log base 3 of 81. Using the steps mentioned above, press “LOG” key, enter 3 as the base, then enter 81 as the argument, and finally press “=” to get 4 as the result.

Finding the value of logarithms has never been easier, thanks to the TI-73 calculator.
