Where we use logarithms in our daily life?
Using Logarithmic Functions Some examples of this include sound (decibel measures), earthquakes (Richter scale), the brightness of stars, and chemistry (pH balance, a measure of acidity and alkalinity). Let’s look at the Richter scale, a logarithmic function that is used to measure the magnitude of earthquakes.
Is log normally base 10?
The base-10, or “common”, log is popular for historical reasons, and is usually written as “log(x)”. For instance, pH (the measure of a substance’s acidity or alkalinity), decibels (the measure of sound intensity), and the Richter scale (the measure of earthquake intensity) all involve base-10 logs.
What is the 10 3 1000 written in log form?
In the example 103 = 1000, 3 is the index or the power to which the number 10 is raised to give 1000. When you take the logarithm, to base 10, of 1000 the answer is 3. So, 103 = 1000 and log10 (1000) = 3 express the same fact but the latter is in the language of logarithms.
Why do we need logarithms?
Logarithms are a convenient way to express large numbers. (The base-10 logarithm of a number is roughly the number of digits in that number, for example.) Slide rules work because adding and subtracting logarithms is equivalent to multiplication and division.
What are the 12 rules of Being Human?
The twelve rules contains wisdom that can help guide you through the process of personal development. 1. You will receive a body. You may like it or hate it, but it will be yours the entire period. 2. You will learn lessons. You are enrolled in a full-time informal school called Life.
What are the rules of life on Earth?
Rule One: You will receive a body. You may love it or hate it, but it will be yours for the duration of your life on Earth. You will be presented with lessons. You are enrolled in a full-time informal school called ‘life.’ Each day in this school you will have the opportunity to learn lessons.
Is the logarithm of base 10 without a subscript?
Without a subscript a logarithmic expression is base 10. The logarithmic expression is asking 10 raised to what power equals 1000 or what is x when Rewrite the logarithm in division. As a log property, we can pull down the exponent of the power in front as the coefficient. Cancel out the .
How to evaluate a base 10 logarithmic expression?
Evaluate the following expression: Without a subscript a logarithmic expression is base 10. The logarithmic expression is asking 10 raised to what power equals 1000 or what is x when Rewrite the logarithm in division. As a log property, we can pull down the exponent of the power in front as the coefficient. Cancel out the .
