​

Answer 1

Answer:

1.irrational

2.a×b

I am not sure about second answer

Answer 2

Answer:

1.

Step-by-step explanation:

The product or quotient of rational

and an irrational number is irrational

7. If a and b are two numbers then H

C F(a,b) ~ LCM(a,b) is

(1x2=2)

HCF by using the prime factorization method.

2.Step1:

Find the prime factorization of each of the number

Step2:

The product of all common prime factor is the HCF

Here,

⇒a=x×x×y×y

⇒b=x×y×y

common Factors are x×y×y

Thus ,

HCF(a,b)=xy
