1.

(4√6) × (6√24) what type of expression is this1. Imaginary 2. Rational 3. Irrational4. None of these

Answer» Correct Answer - Option 2 : Rational 

Concept used:

Rational numbers are those numbers that can be expressed in p/q form where p and q are integers and q ≠ 0, example:- 2/3, 15, 0 etc.

Irrational numbers cannot be expressed in p/q form (i.e. they are no rational), example:- √2, √5 etc.

An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i (iota)

Calculation:

(4√6) × (6√24) = 6 × 4 × √6 × √24

⇒ 24√144

⇒ 24 × 12 = 288

288 can be expressed as 288/1 

⇒ 288 is a rational number

∴ The given expression is a rational number
