FAQs on Basic Concept and Questions of Power and Index Video Lecture - Quantitative Techniques for CLAT

1. What is the concept of power and index?
Ans. Power and index are mathematical operations used to represent repeated multiplication. The power represents the number of times a base number is multiplied by itself, while the index represents the root of a number.
2. How do you calculate the power of a number?
Ans. To calculate the power of a number, you raise the base number to the exponent. For example, if the base number is 2 and the exponent is 3, you calculate 2 raised to the power of 3, which is equal to 2 x 2 x 2 = 8.
3. What is the difference between power and index?
Ans. The power represents the number of times a base number is multiplied by itself, while the index represents the root of a number. In simpler terms, power indicates how many times a number is multiplied, whereas the index indicates the degree of a root.
4. How do you calculate the index of a number?
Ans. To calculate the index of a number, you find the root of the number. For example, if the index is 2, you calculate the square root of the number. If the index is 3, you calculate the cube root of the number.
5. How do power and index relate to each other?
Ans. Power and index are inverse operations of each other. When a number is raised to a power, the inverse operation is finding the root of that number with the corresponding index. Similarly, when a number is taken to a certain index, the inverse operation is raising that number to the power of the corresponding index.
