Multipyling integers with a variable??

Question

Please help me!!! 2n x 1 (multiplying)

Answer 1

2n x 1 = 2n

2n x 2 = 4n

2n x 2n = (2 x 2) x (n x n) = 4(n^2) = 4n^2

2n x n = 2n x 1n = (2 x 1) x (n x n) = 2(n^2) = 2n^2

2n is the same as writing (2)(n) or (2+0)(n+0), you use the same rules but in shorthand.

Answer 2

n=.5?

Answer 3

2n * 1 = 2n since anything multiplied by 1 stays the same

On the other hand 2n* 2 = 4n

Just multiply the like terms 2&2

2n * n = 2n²

Multiply the like terms n&n n*n= n²

Something a little harder....

2n * 2n * 6 *n

Multiply 2n & 2n = 4n²

4n² * 6 * n

Now mulitiply the like terms 6 & 4 = 24

24n² * n

Multiply the like terms n² & n = n³

Final answer: 24n³

NOTE: If you multiply a variable like terms by itself the exponent will grow by one but if you multiply: n² * n²  Add the squares so it'll be n^4

Hope this helped!! :]
