Answer:
1 / sqrt(5) + 5 - sqrt(2)
Step by step explanation:
To simplify the given expression, we need to combine like terms. We can simplify the terms with root 5 and the constant terms separately.
First, let's simplify the terms with root 5:
4 / sqrt(5) - 3 / sqrt(5)
We can combine these terms by finding a common denominator, which is sqrt(5):
(4 - 3) / sqrt(5) = 1 / sqrt(5)
Next, let's simplify the constant terms:
5 - sqrt(2)
Therefore, the simplified expression is:
1 / sqrt(5) + 5 - sqrt(2)
