Question

The solution to 2 * 27 will be what kind of number?

A. Prime
B. Odd
C. Perfect square
D. Even

Answer 1

Answer: Hello mate!

Let's analyze the options:

A) prime, a prime number is a number that only can be divided by 1 and itself, if you look at the number 2*27, you can see that this number can be divided by 2 and 27, then this number is not prime.

B) An odd number has the form m= 2*n + 1 where n is an integer number.

in this case, we have 2*27, so this number is not odd.

C) perfect square, 2*27 = 54, we know that 7*7 = 49, and 8*8 = 65

so 2*27 lays in between two consecutive perfect squares, so 2*27 can not be a perfect square.

D) an even number has the form 2*n, where n is an integer.

n = 27 is this case, so 2*27 = 54 is an even number.

Answer 2

Answer: Even

Explanation:

The given product is
`2*27`

When we solve the given product we get,
`2*27=54`

Now, 54 is not a prime number since it has more than two factors such as 2 and 27.

[ ∵ A prime number is a whole number greater than 1 and it has only two factors which are 1 and itself. ]

It is even not odd since its last digit is an even number.

54 cannot be written as
`n* n`, for any natural number n, therefore, it is not a perfect square.
