All real numbers (except zero) have exactly how many real cube root?
-
One
-
Two
-
Three
-
Four
Correct Answer
A. OneExplanation
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).Rate this question:

-
Latin mathematicians
-
English mathematicians
Correct Answer
A. Babylonian mathematicsExplanation
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.Rate this question:

..... 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.
-
Pythagoras
-
Plato
-
Brutus
-
Caesar
Correct Answer
A. PlatoExplanation
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.Rate this question:
