## FAQs on Golden Rules of Solving Square and Cube Root for CAT - 2 Video Lecture - Quantitative Aptitude (Quant)

 1. What are the golden rules for solving square and cube roots in the CAT exam?
Ans. The golden rules for solving square and cube roots in the CAT exam are as follows: 1. Memorize the squares and cubes of numbers from 1 to 30 to save time during calculations. 2. Use prime factorization to simplify the given number before finding its square or cube root. 3. Break down the given number into its factors and group them in pairs to find the square or cube root. 4. Use estimation techniques to quickly approximate the square or cube root when the options are available. 5. Practice regularly to improve speed and accuracy in solving square and cube root problems.
 2. How can I simplify a given number before finding its square or cube root?
Ans. To simplify a given number before finding its square or cube root, you can use prime factorization. Prime factorization involves breaking down the number into its prime factors. By simplifying the number in this way, you can reduce the complexity of the calculation required to find the square or cube root.
 3. Can approximation techniques be used to find square and cube roots?
Ans. Yes, approximation techniques can be used to find square and cube roots. When the options are available, you can estimate the square or cube root of a number to quickly identify the closest approximation. This can be particularly helpful in time-constrained exams like CAT, where accuracy and speed are both important.
 4. How can I improve my speed and accuracy in solving square and cube root problems?
Ans. To improve your speed and accuracy in solving square and cube root problems, regular practice is key. Solve a variety of problems involving square and cube roots to become familiar with different patterns and techniques. Memorize the squares and cubes of numbers from 1 to 30 to save time during calculations. Additionally, learn and apply the golden rules mentioned in the article to solve problems efficiently.
 5. Is it necessary to memorize the squares and cubes of numbers for the CAT exam?
Ans. While it is not mandatory to memorize the squares and cubes of numbers for the CAT exam, it is highly recommended. Memorizing the squares and cubes of numbers from 1 to 30 can significantly speed up your calculations and save time during the exam. It allows you to quickly recognize patterns and simplify complex calculations, giving you an advantage in solving square and cube root problems.
