Root 2 is appx. 1.414 and root 3 is appx. 1.732. There are many rational number between that. For instance: 1.5, 1.6, etc.
You can find a cube root by guessing which two root numbers the number comes exactly in between. Then you can decide which root number is closest to it or guess and check to find the number that cubes to it. like the cube root of 27 would be 3. 3 to the power 3 = 27. There is no formula for calculating roots of numbers. It is done by a series of approximations. x^(1/3) = exp (ln (x)/3)
to find the square root of a number you need to find the number that multiplied by its self is that number example: the square root on 9 is 3 it is 3 because 3 x 3 - 9
There is no real way to find a square root of any number mentally. The best way to estimate is to think of easy squares near the number. 312 = 961, and 322 = 1024, so the square root of 983 has to be between those two. Using a calculator, we can find that it's 31.35
Find the difference between the two numbers, then add an irrational number between zero and one, divided by this difference, to the lower number. Such an irrational number might be pi/10, (square root of 2) / 2, etc.
Cube root.
Root 2 is appx. 1.414 and root 3 is appx. 1.732. There are many rational number between that. For instance: 1.5, 1.6, etc.
Take the square root of any number between 3 and 4 - for example, the square root of 3.1, 3.5, 3.8, etc.
The square root of any number between 64 and 81.The square root of any number between 64 and 81.The square root of any number between 64 and 81.The square root of any number between 64 and 81.
To find the cube root of a number, enter the number followed by ^(1/3).To find the cube root of a number, enter the number followed by ^(1/3).To find the cube root of a number, enter the number followed by ^(1/3).To find the cube root of a number, enter the number followed by ^(1/3).
2.4494897Answer 2.The number above is indeed rational, but it is not between root 2 and root 3.To find a rational number that is in the range, calculate the two roots and write them down. Then write down any terminating decimal that is larger than root 2 and smaller than root 3. Bingo.
It is somewhere between 3 and 4. You can get a better approximation by using your calculator to get the square root of 11.

Square root of 3 is approximately 1.732.Square root of 5 is approximately 2.236.So, you have the inequality: 1.732
Every number is a square root of some number. So any number between 5 and 6 is a square root.
There are infinitely many of them. In fact there are more of them in that interval than there are rational numbers in total.
