Answer:

yes

Step-by-step explanation:

Let's call the first integer n and let's compute.n^2 + (n+1)^2 + (n+2)^2 +(n+3)^2 = \\n^2 + \\n^2+2n+1 + \\\ n^2+4n+4 + \\\ n^2+6n+9+\\\ n^2+8n+16  =\\4n^2+20n +30 = 2 (2n^2+10n+15)

Which is indeed of the form 2(something), so it is even.

What is 12 to the 2nd power
Alex Ar [27]

Answer: 144

Step-by-step explanation: The problem shown here can be read as "10 to the 2nd," oe "12 to the 2nd power."

The 12 is called the base and the 2 that is raised up is called the exponent.

The exponent of 2 tells us that we multiply our base 2 times.

So we have 12 · 12 which is 144.

The numbers that we multiply together are called factors so in this problem, we have 2 factors of 12.
