Cube Roots is studied in ....
Correct Answer
A. Mathematics
Explanation
Cube roots are studied in mathematics. In mathematics, cube roots refer to finding the number that, when multiplied by itself twice, gives the original number. This concept is an important part of algebra and number theory. It is used in various mathematical calculations and problem-solving techniques. Therefore, cube roots are a topic specifically studied in mathematics.
2.
All real numbers (except zero) have exactly how many real cube root?
Correct Answer
A. One
Explanation
All real numbers (except zero) have exactly one real cube root because for any real number (except zero), there is only one number that when cubed will result in the original number. This is because the cube root is the inverse operation of cubing a number. For example, the cube root of 8 is 2 because 2 cubed equals 8. Therefore, there is only one real cube root for any given real number (except zero).
3.
The calculation of cube roots can be to traced back to .....
Correct Answer
B. Babylonian mathematics
Explanation
The calculation of cube roots can be traced back to Babylonian mathematics. The Babylonians were advanced mathematicians who developed a sophisticated number system and made significant contributions to various mathematical concepts, including the calculation of cube roots. They used a method known as the "duplation method" to approximate cube roots, which involved iteratively doubling the given number until it approached the desired cube root. This method was later refined and adopted by other ancient civilizations, including the Greeks, but its origins can be traced back to Babylonian mathematics.
4.
The calculation of cube roots can be to traced back to Babylonian mathematicians from as early as 1800 BCE.
Correct Answer
C. 1800 BCE
Explanation
The correct answer is 1800 BCE. The calculation of cube roots can be traced back to Babylonian mathematicians from as early as 1800 BCE.

..... posed the problem of doubling the cube, which required a compass-and-straightedge construction of the edge of a cube with twice the volume of a given cube.
Correct Answer
B. Plato
Explanation
Plato, the ancient Greek philosopher, posed the problem of doubling the cube. This problem involves constructing the edge of a cube with twice the volume of a given cube using only a compass and straightedge. Plato's interest in geometry and mathematics is well-known, and he made significant contributions to these fields. Therefore, it is likely that he would have posed such a problem.
6.
In what year did Plato posed the problem of doubling the cube, which required a compass-and-straightedge construction of the edge of a cube with twice the volume of a given cube?
Correct Answer
D. 4th Century BCE
Explanation
Plato posed the problem of doubling the cube in the 4th Century BCE. This problem involved constructing the edge of a cube with twice the volume of a given cube using only a compass and straightedge.
7.
The Greek mathematician Hero of Alexandria devised a method for calculating cube roots in the .....
Correct Answer
A. 1st century CE
Explanation
The correct answer is 1st century CE. This is because Hero of Alexandria, a Greek mathematician, devised a method for calculating cube roots during this time period.
8.
In .... Aryabhatiya, a mathematician-astronomer from the classical age of Indian mathematics and Indian astronomy, gave a method for finding the cube root of numbers having many digits in the Aryabhatiya.
Correct Answer
A. 449 CE
Explanation
Aryabhatiya is a mathematical treatise written by the mathematician-astronomer Aryabhata. In this treatise, Aryabhata provided a method for finding the cube root of numbers with multiple digits. The correct answer, 449 CE, indicates the year in which Aryabhatiya was written and the method for finding cube roots was presented.
9.
Mathematics, as a course is studied in ....
Correct Answer
A. School
Explanation
Mathematics is studied in school because it is a fundamental subject that provides students with essential problem-solving and critical thinking skills. It helps develop logical reasoning and analytical abilities, which are important for various careers and everyday life. Schools provide a structured environment where students can learn and practice mathematical concepts, theories, and techniques. Furthermore, mathematics is a core subject in most educational systems, and it is necessary for academic progression and further study in fields such as science, engineering, finance, and technology.
10.
Who among them is not a mathematician?
Correct Answer
C. Barack Obama
Explanation
Barack Obama is not a mathematician because he is a politician and former President of the United States, not known for any contributions or expertise in the field of mathematics. On the other hand, Albert Einstein, Isaac Newton, and Pythagoras are renowned mathematicians who have made significant contributions to the field.
