28–√+38–√

Answer 1

[AI-generated answer — Bot GPT 3.5]

To evaluate the expression 28 - √(38) - √( ), you would first simplify the square roots and then perform the subtraction.

√(38) is an irrational number, as it cannot be expressed as a fraction or a terminating decimal. However, it can be approximated to 6.1644.

28 - √(38) ≈ 28 - 6.1644 ≈ 21.8356

Therefore, the simplified expression is approximately 21.8356.

To simplify the expression 28–√+38–√, we need to combine like terms.

Step 1: Start by combining the two square roots.
√ + √ = 2√

Step 2: Now we have 28 - 2√ + 38. Combine the numbers.
28 + 38 = 66

Step 3: Bring back the simplified square root.
66 - 2√

So, the simplified expression is 66 - 2√.

To evaluate the expression 28 – √(38 – √x), we need to follow the order of operations, which is typically represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, let's simplify the expression inside the first square root: 38 – √x
Since we do not have any information about the value of x, we cannot directly simplify this expression any further.

Now, let's simplify the expression outside the square root: 28 – √(38 – √x)
Since there are no other operations involved here, we cannot simplify this any further as well.

Therefore, the expression 28 – √(38 – √x) cannot be simplified any further without knowing the value of x.
