To simplify the expression 6 + 6–√, we need to perform the mathematical operations in the correct order:

6 is , 6–√ is so, 6 + 6–√ is

To simplify the expression, we need to evaluate the square root first, then perform the addition.

6 - √(6)
First, let's find the square root of 6:
√(6) ≈ 2.449

Now, we can substitute this value back into the expression:
6 - 2.449 ≈ 3.551

So, the simplified expression is approximately 3.551.

To simplify the expression 6 + 6–√, we need to evaluate the square root first. If there are no parentheses indicating a specific order of operations, we can evaluate the square root first.

Since √ is equivalent to raising a number to the power of 1/2, we can rewrite the expression as:

6 + 6 - (√6)

Next, we can evaluate √6, which simplifies to approximately 2.45:

6 + 6 - 2.45

Finally, we can perform the addition and subtraction:

12 - 2.45 = 9.55

Therefore, 6 + 6–√ simplifies to approximately 9.55.
