Given the perfect square expression
. Apply perfect square formula:

Knowing laws of exponent is mandatory when it comes to algebra. Recall that:

Apply laws of exponent to simplify the terms or expression:

Since there are no like-terms to do operation with (these terms have different degrees so they are not considered to be like-terms.) Therefore, the final answer is:

Answer:

Answer:

Step-by-step explanation:
Given that,
An airthmetic sequence,
261,256,251
We need to find the 50th term.
We have,
first term, a = 261
common difference = 256-261 = -5
The nth term of the AP is given by :

So, the 50th term of the sequence is 16.
The answer is 7.8
