No 18 is not. It is a abundant number.
18 is abundant
It is a square number but not a perfect square. The nearest perfect squares, on either side, are 4^2 = 16 and 5^2 = 25. Since there is no integer between 4 and 5 and the square is a strictly monotonic function, 18 cannot be a perfect square.
Yes, in so far as all numbers are squares (of some number). But it is not a perfect square.
The sum of the 1st perfect number and 2nd perfect number is. . . 34!
No, 18 is not a square number because a square number is an integer that can be expressed as the product of an integer multiplied by itself. The square numbers closest to 18 are 16 (4 × 4) and 25 (5 × 5), and 18 does not fall between these two perfect squares. Additionally, there is no integer whose square equals 18.

It is 2 times 18 = 36 which is a perfect square number because 6 time 6 = 36

5607 + 18 = 5625, a perfect square. The perfect square of a square root is the number you started with.
The square root of 18 is an irrational number because it cannot be expressed as a fraction.
It is: 9 and 9 times 18 = 162

49 x 14 x 18 is not a perfect square. This is because a prime factorization of 49 x 14 x 18 contains 3 sevens. The prime factorization of any perfect square must have an even amount of each prime number.
