A factor tree has factors, not square roots - unless they are integers.
Factor it. Once you find a third factor, it's composite.
Oh, dude, the third square root of 1000 is approximately 10. Why do you even need to know that? Are you planning on calculating square roots at a party or something? Like, chill out, man.
One perfect square times another perfect square does produce a third perfect square.
3 x 3 = 9
The sum of 32 is 9.
The only common factor of those two terms is the number three, giving you: 3(x3 - 8y3)
a square is 2 dimensional and a cube is 3 dimensional
A factor is a number which, when multiplied by another number makes a third number. The factors of 9 are 3 and 3. The factors of 12 are 2, 2 and 3. SO 3 is a common factor of 9 and 12.
A square is called "second power" because a square number is a number, in which its factors are "2" of the same number, ( ex, 1 x 1, 2 x 2, 3 x 3,etc). So, in other words, the "first" factor is a certain number, and the "second" number is the same number. You are using the same number 2 times in order to get the product, which is the square number.A square number physically forms a square. You can see this by taking 1 inch square pieces of paper and taking any square number ( 2, 4, 16, etc) and making it into an array - it is a perfect square. If you take a number, which is not a square number, it cannot pysically form a square, no matter how you try.A cubed number is the same, it physically forms a cube.
36
There is no easy way. You will have to try dividing it by the smallest prime (2), then the next one (3) and continue until you have tried out the all the primes up to and including the square root of the number. You do not need to find the quotient, you only need check for divisibility.
If it has more than two factors. If you find a third factor, you know.
