x2=3x+4
x2-3x-4=0
(x-4)(x+1)=0
x=4 or x=-1
Since you specified a positive integer, the number in question is 4.
Another positive integer
Try squaring different integers (hint: in this case, the integers will be fairly small). If you find that the square of one integer is less than 27, and the square of the next integer is more than 27, you have your answer.
The numbers are 14, 16 and 18.
3. The square root of a number is the number that when multiplied by itself, will give you the original number. Therefore, if you multiply the square root of three by itself, you will get three. A more clear example using whole numbers: the square root of nine times the square root of nine is three times three, which gives you nine, your original number.
more positive, most positive
A positive integer is an integer to the right of zero on the number line. It is more then zero
Another positive integer
It might seems like it, but actually no. Proof: sqrt(0) = 0 (0 is an integer, not a irrational number) sqrt(1) = 1 (1 is an integer, not irrational) sqrt(2) = irrational sqrt(3) = irrational sqrt(4) = 2 (integer) As you can see, there are more than 1 square root of a positive integer that yields an integer, not a irrational. While most of the sqrts give irrational numbers as answers, perfect squares will always give you an integer result. Note: 0 is not a positive integer. 0 is neither positive nor negative.

A square number, or perfect square, is the square of an integer. 232 is less than 572, 242 is more, so it is not the square of an integer.
Not necessarily, for example: If you subtract 3 from 4, then you get +1. But if you subtract 4 from 3, you get -1. The answer will always be an integer, but you cannot make a general statement about the sign, without knowing more information.
Usually they are. More specifically, if you take the square root of a positive integer, there are only two possibilities:* If you take the square root of a perfect square, you get a whole number. * In all other cases, you get an irrational number.
A positive integer with more than two factors.
A prime number is a number with two positive integer factors, while a composite number has more than two positive integer factors. Since the number 0 has no positive integer factors, and the number 1 has just one positive integer factor (itself), neither of these are prime.
Because whatever integer lays claim to that title is smaller than "one more".
