Have you ever wondered how population growth is measured? Or have you ever wondered what maths concepts are used in doing so? The answer is Logarithms! Students of math class 8 must have come across the idea of logs. It is a fascinating maths topic that is frequently and widely used in science and technology and in the world of finance. Students who aspire to pursue maths in future to become successful engineers or finance experts must be clear with log concepts while preparing for their cbse class 8 preparation. But how to prepare for the 8th board exams?
If you are worried about board preparation class 8, then fret not because Cuemath's Log Table guide is a groundbreaking resource for students struggling to grasp math class 8 logarithms. Their log table guide simplifies the complex concepts of logarithms, providing students with a comprehensive and easy-to-use guide that simplifies understanding. Therefore, if you struggle with logs while preparing for maths class 8 exams, read ahead to simplify math with Cuemath’s comprehensive log table guide.
What are Logarithms?
Logarithms might sound intimidating but in reality logarithm is a mathematical concept that is used to simplify complex maths problems. In simpler terms, the logarithm of a number is the power to which the base must be increased to produce that number. Therefore, if a^b = c, then log base a of c = b. Doesn’t that make it sound exciting and less intimidating?
The notation for logarithms is log base a of b, where a is the base and b is the number. Logarithms include certain properties including the product rule, quotient rule, power rule, and change of base rule.
The product rule states that log base a of (b*c) = log base a of b + log base a of c.
The quotient rule states that log base a of (b/c) = log base a of b - log base a of c.
The power rule states that log base a of b^c = c*log base a of b.
The change of base rule states that log base a of b = log base c of b / log base c of a.
How to Simplify Maths with Cuemath’s Comprehensive Log Table Guide?
Are you starting with your board preparation class 8 and wondering how to prepare for the 8th board exam? Then fret not. By using Cuemath’s comprehensive log table guide students can easily solve complex problems of math class 8 and score high in maths exams.
Familiarise Yourself with Cuemath’s Log Table: Cuemath’s log table is a comprehensive maths reference table that easily provides the logarithms of numbers. This log table consists of columns for the numbers 1 to 10, and rows for the logarithms equivalent to different decimal values.
Identify the Number for which you need the Logarithm: Log calculations can be tricky if you do not start by identifying the number for that you need the Logarithm. Hence, it is essential to identify numbers with multiple decimal values or more significant digit numbers.
Locate the Number in Cuemath’s Log Table: The next step after successfully identifying the number you need the logarithm for is navigating through the logarithmic table and locating the number. Look for the column that corresponds to the first digit of the number and find the row that matches the remaining digits in case of decimal
Read the Logarithm Value: The next step after locating the log table, is reading the corresponding logarithm value. This value represents the exponent to which a base (usually 10) must be raised to obtain the original number.
Use Logarithm Properties: Logarithm properties consisting of the product rule, quotient rule, and power rule, is helpful in simplifying maths calculations for math class 8 students. Therefore, students can use cuemath’s comprehensive log table guide to easily solve maths problems.
Check the Sign and Decimal values: A comprehensive log table, such as that of Cuemath, will assist you in determining the positive and negative logarithm values, that will in turn help in determining the sign of the original number. Moreover, you can adjust the decimal values in accordance to your calculations.
Practice and Verify Results: Referring to a log table requires practice and correct technique to interpret the results and make accurate calculations. In case you don’t have enough practice in using a log table, it is recommended to use a calculator to ensure error-free results.
In conclusion, mastering the concept of logarithms is crucial for students studying math class 8, as it is widely used in various fields such as science, technology, and finance. There are many real-world applications of logarithm such as measuring the intensity of earthquakes using the Richter scale that is based on a log scale that helps in measuring the magnitude of an earthquake.
In the field of finance, the most common use of logarithms is calculating compound interest. In science, it is used to record and calculate population growth. If you want to simplify learning maths, register with Cuemath today for personalised tutoring for a bright future in mathematics!
