Question

Which of the following is irrational number
?
A)√9 B) 0 C) 3√8 D) -√0.64​

Answer 1

Answer:

the answer wil be C) 3×8^1/2

Step-by-step explanation:

A)9^1/2 = 3 = 3/1

B)0 = 0/1

D)- (0.64)^1/2 = - 0.8 = - 8/10

these numbers can be written in the form of p/q , where p and q are integers. So, 9^1/2 , 0 and - (0.64)^1/2 are rational numbers. But 3 × 8^1/2 does not belong to a rational number.
