Question

which of the following is an irrational number. a) √16. b) √(12/3). c) √12 d) √100​

Answer 1

Answer:

c)

Step-by-step explanation:

Other values are perfect squares except 12

Answer 2

√12 is an irrational number. (Option c)

• Of all values given above, only √12 is irrational.
• We cannot represent it in the p/q form and it will always consist of a value under the root.
• It can also be written as 2√3.
• Also, √16 is 4, √(12/3)  is 2, and √100 is 10.
• All these can be written as p/q, where q=1.
• So, only option c is not rational.
