Because you are squaring numbers, the only way to get double is by using the square root of 2 which is 1.414.
A good example of this is paper sizes.
A4 is 210x297
A3 is double the size of A4 but to get that you need to multiply the sides by 1.414. That gives 297x420
But if you double each side of A4 you get 420x594 which is A2 and that is 4 times as big as A4 not 2 times as big.

∙ 8y agoTake a look at the corresponding square roots (of the square numbers). If n^2 is a perfect square (the square of "n" - note: using "^" for exponentiation), then twice that number is the 2n^2. The square root of that is root(2) x n. And since root(2) (the square root of 2) is irrational, it follows that root(2) x n is not a whole number.

Why cant you evaluate square root -25?
You cannot in real numbers because the square of any number, negative or positive, is positive. However, -25 does have a square root in complex numbers: it is + or - 5i where i is the imaginary square root of -1.
What is it called when a square is a rectangle but a rectangle cant be a square?
it means that a square is not a rectangle
Why cant a natural number be divided by 0?
0 is nothing, you cannot divide a number by nothing, it would be the same as putting the number then the divide symbol and not putting another number in.
Why cant 10 to the power of 50 3 be a square number?
10 = 2*5 (prime decomposition)So for a power of 10 to be a square means that the powers its factors must be even. A power of 10 is a square if it contains an even number of factors of 2 and 5. Since 503 is an odd number, 10^503 has an odd number of powers of 2 and 5, so it can't be the square of an integer.
Why is 17 not a square number?
because you cant square a number to get 17, that's why xD
Square root of -12 plus square root of 300?
you cant take the square root of a negative number
What is a not real number?
a number that cant be written on a number line. (ex. √-1) (the check is a square root sign)

What is the difference between odd nos and prime nos?
odd is a number you cant halve a prime number is a number that you can double itself and it is odd
Is 2 the GCF of 12?
you cant have the GCF of just one number. you need to compare it to another number
Is 18 toothpicks enough to form 5 quadrilaterals if no quadrilateral shares a toothpick with another quadrilateral?
Yes, if a generic square is made, and a toothpick along the vertical and horizontal line of symmetry, and then another generic square. 18 is enough to form it, and so is any double-digit number.JK they cant share any. But maybe, if you use more than toothpicks
Why is it impossible to find the square root of a negative?
Because for a number to be a square number it must have a number which when multiplied by it self=that number. For example: 36 is a square number because 6x6=36 16 is a square number because 4x4=16 A negative number such as -16 is not a Square Number because -4x-4=16 not -16 because a negative times a negative is a positive. -4x4=-16 but these numbers aren't the same therefore -16 isn't a square number. This is why negative numbers cant be Square Numbers
What is the Square root of 231 in radical form?
radical 231; no perfect squares factor into this number. It cant be simplified
What is an rectangle?
a rectangle cant be a square but a square can be a rectangle
Is the square root of -25 irrational or complex?
you cant get the square root of a negative number. nothing times itself would equal a negative number. if you have √-25 then its not possible. If you have -√25 then you take the square root of 25 and make it negative, so then it would be -5
