Question

How do you solve for x in a logarithmic function using a calculator?

Answer 1

To solve for x in a logarithmic function using a calculator, enter the value inside the logarithm and press the corresponding logarithm button. Then, take the inverse logarithm to find x.

Step-by-step explanation:

To solve for x in a logarithmic function using a calculator, you can use the following steps:

1. First, identify the base of the logarithmic function. Common bases are 10 and e (the natural logarithm).
2. Enter the value inside the logarithm into the calculator.
3. Press the corresponding logarithm button on the calculator, either log or ln (for natural logarithm).
4. The calculator will display the logarithm of the value.
5. To find x, take the inverse logarithm of the displayed value. For base 10, use 10^x. For base e, use e^x.

For example, let's solve the logarithmic function log base 10 of 100:

1. Enter 100 into the calculator.
2. Press the log button.
3. The calculator will display 2, which is the logarithm of 100.
4. To find x, take the inverse logarithm by calculating 10^2, which equals 100.
5. Therefore, x is equal to 100.
