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.
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.
The sum of the 1st perfect number and 2nd perfect number is. . . 34!

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