Answer 2

Answer:

The value of 2 root 5 + root 5 = 6.708203...

Step-by-step explanation:

Irrational number: Non-terminating and non-repeating decimal numbers are known as irrational numbers.

For example √2, √3, √5, etc. are known as irrational numbers.

Here √5 is an irrational number.

Given,

2 root 5 + root 5 = 2√5 + √5

Calculation,

2√5 + √5

Now, we take √5 common from both the terms

⇒ √5(2 + 1)

⇒ √5 (3) (As 2 + 1 = 3)

⇒ 3√5

⇒ 3 × 2.23606... (As the value of √5 = 2.23606...)

Now we multiply 3 and 2.23606...

We get:

⇒ 6.708203...

Therefore, the value of 2 root 5 + root 5 = 6.708203...
