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.
