Answer:
Step-by-step explanation:Let us assume that 3-√5 is rational.
3-√5=p÷q where p and q are integers and qnot = 0and p and q are co prime.
3-√5 = p÷q
-√5=p÷q-3
√5=3q-p whole ÷ q
but it contradicts to the fact√5 is irrational - proove it if it is a question of 3 or 4 mark
hence our first assumption is wrong.therefore it is proved that 3- √5 is irrational...
