Can the cube root of a two-digit number be a 3-digit number? Support
your answer with proper examples
Answers
The examples :
Cubes between 1 and 100 that are two digit are as follows :
27
64
These are the only two digit number perfect cubes we have.
Their cube roots are as follows :
∛27 = 3
∛64 = 4
From the cube roots above, we see that the cube root of a two digit number gives a one digit number.
The answer is thus no.
The answer is obviously no. But the way we prove it matters.
So, finding a cube-root of any number, not only a two digit number will be definitely less than the original number. So, there's no point of getting a three digit number from cube-root of a 2 digit number.
Now lets prove this mathematically.
The smallest two digit perfect cube is 27 and largest two digit perfect cube is 64.
The cuberoot of both these numbers are 3 and 4 which is one digit.
I hope you're clear with the answer by now.
