1.

2. Prove that 3+25 is irrational​

Answer»

<P>Answer:

So,3+2√5 is equal to AB. In the above expression, “a” & “b” are co PRIME (meaning HCF (a, b) is equal to 1). Now, the expression a−3b2b is a rational NUMBER because the DEFINITION of a rational number states that it is a number which is in the form of pq where p and q are integers and q≠0.
