Question

check (1+root 5 )-(4+root 5 ) as rational or irrational​

Answer 1

Answer:

Rational

Step-by-step explanation:

given (1+√5)-(4+√5)

by removing brackets it changes as

1+√5-4-(+√5)

=1+√5-4-√5

√5 and √5 can each other so it changes as

=1-4

=-3

As -3 is rational number (1+√5)-(4+√5) is also rational.
