To add the expression 28–√+38–√, you can simplify it by combining like terms.
First, let's simplify √ and make it as a whole number. √28 = 2√7, and √38 = √(19*2) = √19 * √2 = √19 * √2.
So the expression becomes: 28 - 2√7 + 38 - √19 * √2.
Next, combine the like terms: 28 + 38 = 66 and -2√7 - √19 * √2.
Since √7 and √19 cannot be simplified further, the final expression is:
66 - 2√7 - √19 * √2.
2√8+3√8
To add the expression 28–√ + 38–√, you need to add the numbers separately and combine the square roots separately. Let's break it down step by step:
Step 1: Add the numbers:
28 + 38 = 66
Step 2: Combine the square roots:
√ + √ = 2√
Step 3: Combine the results from Step 1 and Step 2:
66 + 2√
Therefore, the simplified form of the expression 28–√ + 38–√ is 66 + 2√.
To add the given expression, follow these steps:
Step 1: Simplify the square root terms separately.
√28 can be simplified as √(4 x 7), which further simplifies to 2√7.
√38 can be simplified as √(2 x 19), which cannot be simplified further.
Step 2: Add the simplified square root terms:
2√7 + √38.
Since the square root terms are not like terms (they do not have the same number inside the root), they cannot be combined further.
Therefore, the addition expression is 2√7 + √38.
