Question

Show that√5 is an irrational number. Hence show that 2+3√5 is also an irrational number

Answer 1

Answer:

Hi there

here is your answer

Step-by-step explanation:

For 2+3√5 you just have to transfer all the rational number to the LHS

i.e; a=2+3√5

a-2/3=√5

then prove that √5 is a irrational no.

with the same steps and at last the whole question that is 2+3√5 will be proved as irrational no.
