Logarithms are mathematical functions that help us solve equations involving exponents. They are commonly used in various fields such as science, engineering, and mathematics. In this article, we will explore the logarithm expression: log 1/2 462, and discuss its equivalent form.
What is Logarithm?
A logarithm is the inverse function of an exponential. In other words, it tells us what exponent we need to raise a specific base number to get a certain value. The general form of a logarithm is:
log_base(value) = exponent
For example, in the expression log_2(8) = 3, the base is 2, the value is 8, and the exponent is 3. This means that 2 raised to the power of 3 is equal to 8.
Understanding Log 1/2 462
The expression log 1/2 462 can be interpreted as the logarithm of 462 with the base of (1/2). In other words, it tells us what exponent we need to raise 1/2 to in order to get 462.
To find the equivalent form of log 1/2 462, we can rewrite it in exponential form. The conversion rule for logarithms is:
log_base(value) = exponent is equivalent to base^exponent = value
Applying this rule to log 1/2 462, we get:
(1/2)^exponent = 462
Now, we need to solve for the exponent that will make (1/2) raised to that power equal to 462.
Finding the Equivalent Form
To find the equivalent form of log 1/2 462, we need to solve for the exponent in the equation: (1/2)^exponent = 462.
- Step 1: Start by rewriting 462 as a power of 2 for easier calculation.
- 462 = 2^x, where x is the unknown exponent.
- 462 = 2 * 231 = 2^1 * 2^7 = 2^8
- Now, we have that 462 is equivalent to 2 raised to the power of 8.
- Step 2: Substitute 462 as 2^8 in the equation (1/2)^exponent = 2^8.
- (1/2)^exponent = 2^8
- Step 3: To find the value of the exponent, equate the two sides of the equation.
- exponent = 8
Therefore, the expression log 1/2 462 is equivalent to log2(462) = 8.
Conclusion
In conclusion, we have discussed the concept of logarithms and how to find the equivalent form of log 1/2 462. By converting the given expression into exponential form and solving for the unknown exponent, we found that log 1/2 462 can be rewritten as log2(462) = 8.
Logarithms play a crucial role in mathematics and provide a powerful tool for solving exponential equations efficiently. Understanding their properties and applications can greatly benefit students and professionals in various fields.
