No - the square root of 40 is not a rational number. Rounded to ten decimal places, it is equal to 6.3245553203.
All numbers have square roots. You may have meant which factors of 40 are perfect squares. That's 1 and 4.
A number will have an odd number of factors if and only if one of those factors is the square root of the number. This is because any factor of a number you can find must pair up with another factor of that number, and multiply to give the number. The only exception is when the factor would be paired with itself. In other words, be the square root. 81 is a square number, and so the factor 9 (square root of 81) will not pair with any other factor, meaning 81 will have an odd number of factors. 40 has an even number of factors, because it is not a square number, and so all its factors can pair up.
Six and seven
Take the square root of 1617 and round it up. Take the square root of 5929 and round it down. That gives you the lower and upper range of the numbers which you must square to get the desired perfect squares.
The square root of 40 is an irrational number
irrational
It is an irrational number, and therefore a real number.
The square root of 40 is an irrational number, due to the fact that one could extend the answer to an infinite number of decimal places if one was able to.
sqrt(40) or 2*sqrt(10) Evaluating the above will result in a decimal approximation which will be rational, not irrational.
Yes because it can't be expressed as a fraction
It is irrational because it can't be expressed as a fraction
10 times pi, 24 times the square root of 2, plenty more (infinitely more).
