Add 28–√+38–√
To add the given expression, we need to find the square root of 28 and the square root of 38, and then subtract both results.
The square root of 28 is approximately 5.29 (rounded to the nearest hundredth).
The square root of 38 is approximately 6.16 (rounded to the nearest hundredth).
Therefore, the expression simplifies to:
28 - √28 + 38 - √38 = 28 - 5.29 + 38 - 6.16
Simplifying further:
= 62.71 + 31.84
Finally, we can add the numbers:
= 94.55
The result of the given expression is approximately 94.55.
To simplify the expression 28–√+38–√, we can first combine like terms.
Starting with 28–√+38–√, we have two terms with a square root:
1. -√
2. -√
To combine these terms, we add them together: -√ + (-√) = -2√
Now we have 28 - 2√ + 38.
Adding 28 and 38 gives us 66.
Therefore, the simplified expression is 66 - 2√.
To simplify the expression 28 - √(38) - √(we need to follow a specific order of operations:
1. Start by simplifying any square roots present in the expression. In this case, we have the square roots of 38 and 2.
√38 cannot be simplified further since it does not have any perfect square factors.
√2 is an irrational number and cannot be simplified any further.
2. Next, perform the subtraction operations as indicated in the expression:
28 - √38 - √2
We cannot combine the terms 28 and √38 since they are not like terms.
Therefore, the simplified form of the expression 28 - √38 - √2 is:
28 - √38 - √2
