No, it is not a perfect number. The first four known perfect numbers are 6, 28, 496 and 8,128.
The perfect square of 42 is 42 x 42 or 1,764.
No- the closest perfect squares are 36 (perfect square of 6) and 49 (perfect square of 7)
Use the definition of a perfect number! Add the factors; if the sum of all the factors (excluding the number itself) is equal to the number, it is a perfect number, otherwise it isn't.

number was 42
42 is not a cube number.
The sum of the 1st perfect number and 2nd perfect number is. . . 34!
No. The two closest squares are 49 and 36. The square root of 49 being 7 and the square root of 36 being 6. you can conclude that the square root of 42 isn't a perfect square, but it's square root is between 7 and 6.
42/6 = 42 ÷ 6 = 7
you count the 42's until you get to the number 42 you count the 42's until you get to the number 42
Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".
If by 'perfect number' you mean 'perfect SQUARE', then yes. 49 is an odd number and a perfect square.
42 is not a square number but 42^1=42
