## How to Calculate Log Using Simple Calculator

Logarithms are used in various fields of mathematics, science, and engineering. They can be calculated using a simple calculator. This article will guide you on how to calculate logarithms using a simple calculator.

### Select the base of the logarithm

The base of the logarithm is the number that is raised to a power in order to get another number. For example, in the logarithm log2(8), 2 is the base. Select the base of the logarithm you want to calculate.

### Enter the number whose logarithm you want to find

Enter the number whose logarithm you want to find. For example, if you want to find the logarithm of 8 base 2, enter the number 8.

### Press the log button

Press the log button on your calculator. This will give you the logarithm of the number you entered with the selected base.

### Example

Let’s say you want to find the logarithm of 8 base 2. First, select the base 2. Enter the number 8. Press the log button. The result will be 3. Therefore, log2(8) = 3.

### Using the natural logarithm

If you want to calculate the natural logarithm (logarithm base e) of a number, press the ln button on your calculator instead of the log button.

### Example

Let’s say you want to find the natural logarithm of 10. Enter the number 10. Press the ln button. The result will be approximately 2.302585093.

### Using the inverse logarithm

The inverse logarithm (exponentiation) is the opposite of the logarithm. It is used to find the value of a number that has been raised to a power. To find the inverse logarithm of a number, press the 10x button on your calculator.

### Example

Let’s say you want to find the inverse logarithm of 3. Enter the number 3. Press the 10x button. The result will be approximately 1000.

### Using the power function

The power function is used to find the value of a number raised to a power. To use the power function on your calculator, press the x^y button.

### Example

Let’s say you want to find 2 raised to the power of 3. Enter the number 2. Press the x^y button. Enter the number 3. Press equals. The result will be 8.

### Using the square root function

To find the square root of a number, press the square root button on your calculator.

### Example

Let’s say you want to find the square root of 9. Enter the number 9. Press the square root button. The result will be 3.

### Using the exponent function

The exponent function is used to find the value of e raised to a power. To use the exponent function on your calculator, press the ex button.

### Example

Let’s say you want to find the value of e raised to the power of 4. Enter the number 4. Press the ex button. The result will be approximately 54.59815003.

### Using the natural logarithm with the base e

If you want to calculate the natural logarithm of a number with base e, press the ex button on your calculator instead of the ln button.

### Example

Let’s say you want to find the natural logarithm of e. Press the ex button on your calculator. The result will be 1.

### Using the common logarithm

The common logarithm (logarithm base 10) is used to find the power of 10 that gives a particular number. To use the common logarithm on your calculator, press the log button and enter the number you want to find the logarithm for.

### Example

Let’s say you want to find the common logarithm of 100. Press the log button. Enter the number 100. Press equals. The result will be 2.

### Using the inverse function

The inverse function is used to find the reciprocal of a number. To use the inverse function on your calculator, press the 1/x button.

### Example

Let’s say you want to find the reciprocal of 5. Enter the number 5. Press the 1/x button. The result will be 0.2.
