Question

Solve this 1+2/under root 5

Answer 1

Answer:

5 + 2√5/5

Step-by-step explanation:

1 + 2/√5

First, we will take LCM for the above question,

= 1 × √5 / 1 × √5 + 2/√5

= √5/√5 + 2/√5

= √5 + 2 / √5

Now, we will rationalise the denominator by multiplying the above one with √5/√5,

=  √5 + 2 / √5 × √5/√5

= √5(√5 + 2)/√5(√5)

= 5 + 2√5/5

Therefore, 5 + 2√5/5 is the solution of the given question.

Hope this helps you!!!
