Question

Prove that √98 Is irrational Number​

Answer 1

Answer:

Any number that can't be written in p/q form are irrational number

Step-by-step explanation:

here we can't write any root numbers in p/q form so clearly√98 is a irrational number

Answer 2

Answer:

√98 = √ 2 x 7 x 7

= 7√2

√2 is an irrational number.

A rational number multiplied by an irrational number gives an irrational number.

Since 7 is a rational number, 7 x √2 is an irrational number.

Hence √98 is an irrational number.

( It can't be expressed as p/q form, which adds to the existing conclusion)
