Do all square numbers have a odd number of factors?
Yes, because each factor must have another factor to go with it, but the square root of a number can have itself as a pair.
Why does a square number have an odd number of factors?
A square number will have one factor pair that consists of the same number (the square root). In the list of factors, that number will be written once.
Why 81 have an odd number of factors and 40 have an even number of factors?
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.
What is an equal factor?
a square root
What is the repeated factor called?
the square root
Find square root of a number?
first, you take a number. for my example, I'll use 12. 12x12= 144. 144 would be the square number, and 12 would be the square root. clarification: if you multiply a number by itself, the product isn't the square root, the factor is. and if your really stupid, here's this: 12x12=144 F F P F means factor P means product. happy now?
What is the Equal Factor of a number?
A square root.
What number between between 100 and 300 has a square root that is a prime number and the sum of it's digits is an odd number?
There can't be a prime number that has a square root because the square root would be a factor of the number.
A number used as a factor two times?
A number used as a factor two times is a square root.
Is the product of two irrational numbers always an irrational number?
No. The square root of two is an irrational number. If you multiply the square root of two by the square root of two, you get two which is a rational number.
What is a square root of an number?
The square root of an number, is the number that is times by itself to make the product. For example, the square root of 25 is 5 because 5 x 5 equals 25. Or the square root of 144 is 12 (12x12=144)
What is the square root of 247?
The square root of a number is equal to the product of the roots of two factors of that number. -247 can be written as -1x247. The square root of -1 is i. The square root of 247 is approximately 15.716. Thus, the square root of -247 is 15.716i
How would you find the square root of 64.36 using a factor tree?
The square root of 64.36 is an irrational number. Consequently you cannot find the root using a factor tree.
Is there a prime factor greater than the square root of an integer?
No there is not. If you are looking for prime factors of a number and you get to the square root of that number you can stop. Yes, there is. If an integer is not itself a prime, then one of its factors will be less or equal to its square root and the "co-factor" will be greater than or equal to the square root. But both cannot be greater than the square root so, when searching for factors, you can stop when you reach the square root.
What is the difference between a square and a rectangular number?
A square number is the product of the same two integers. A rectangular number is the product of consecutive integers.
Does there exist an irrational number such that its square root is rational?
No, and I can prove it: -- The product of two rational numbers is always a rational number. -- If the two numbers happen to be the same number, then it's the square root of their product. -- Remember ... the product of two rational numbers is always a rational number. -- So the square of a rational number is always a rational number. -- So the square root of an irrational number can't be a rational number (because its square would be rational etc.).
Can you simplify the square root of 52?
Yes. Factor the number, and see if any factor repeats!
