HELP ME PLEASE :( Will mark as brainlist, only correct answers Q: compare and examine the difference between each of the following pairs of expressions.

•2n and 2 + n
•n² and 2n
•2n² and (2n)²

Comment whether each pair of expressions is equal. Explain ur answer.​

None of the pairs of expressions are equal

Step-by-step explanation:

• 2n ≠ 2 +n

2n is the same as 2 times of n (expressed as a multiplication sign), while 2 +n is the addition of 2 to n.

•n² ≠ 2n

n²= n ×n

2n= 2 ×n

• 2n² ≠ (2n)²

Note that in the latter, there is a bracket which means that the square applies to both 2 and n.

(2n)²

= (2)² × n²

= (2 ×2)(n²)

= 4n²

Thus, none of the pairs of expressions are equal.

each side has a different length.
