The expression 3n squared, written as 3n^2, represents three times the square of a variable n. This means you multiply the variable n by itself and then multiply the result by 3. For example, if n is 2, then 3n^2 would be 3 x 2^2 = 3 x 4 = 12.
Oh, dude, you're hitting me with some math now? Alright, so 3n squared is just 3 times n squared. It's like when you triple the value of n squared. So, if n is 2, then 3n squared would be 3 times 2 squared, which equals 12. Math, man, it's everywhere.
Oh, dude, like, 3n times n is just 3n^2. It's like, you take 3 times n, and then multiply that by n again. So, it's basically n squared, but with a 3 in front. Easy peasy, lemon squeezy.
