Question

check whether _5+2√5-√5 is an rational or a irrational​

Answer 1

Answer:

Given, -5 + 2√5 - √5

We shall take √5 common in the 2nd and 3rd terms and solve it

-5  + √5 ( 2 - 1 ) = -5 + √5

As we cannot add or subtract  rational and irrational numbers, we cannot simplify further.

As the number as a whole contains an irrational number, the whole number is an irrational number.
