It looks like you're trying to perform some arithmetic operations involving square roots. However, it seems there might be a misunderstanding or a typo in the expression you provided. The symbol "✓" is usually used to represent the square root of a number. For example, √25 represents the square root of 25, which is 5.

If you meant to write an expression like this:

√11 - √72 + √11 + √72

then you can simplify it as follows:

√11 + √11 + √72 - √72

Since the square root of the same number is being added twice and subtracted twice, these terms cancel each other out:

2 * √11 - 2 * √72

Now, if you want a numerical approximation, you can calculate the square roots and subtract them:

2 * √11 ≈ 6.63324958071 2 * √72 ≈ 16.9705627485

Finally:

6.63324958071 - 16.9705627485 ≈ -10.3373131678

So, the result is approximately -10.337.
