add √31 + √31
its not 2√31
√31 + √31 is 2√31.
To add √31 + √31, we can simplify by recognizing that both terms have the same radical. Therefore, we can combine them.
√31 + √31 = 2√31
So, the sum of √31 + √31 is indeed 2√31.
To add √31 and √31, you can use the basic rules of addition. However, it's important to note that the square root (√) symbol represents a non-perfect square, which means that the number inside the square root cannot be simplified further.
In this case, both √31 terms cannot be simplified, so we can simply add them together:
√31 + √31 = 2√31
So, the answer is indeed 2√31.
