Step-by-step explanation:

(5)

Given Irrational number is √27.

It can be written as : 3√3.

In order to make it a rational number, we have to multiply it with √3.

= 3√3 * √3

= 3 * 3

= 9.

= Rational number.

Therefore, Smallest number is √3.

(6)

Given : 43/2⁴ * 5³

It can be written as,

= (43/2⁴ * 5³) * (5/5)

= (43 * 5)/(2⁴ * 5⁴)

= (43 * 5)/(2 * 5)⁴

= 215/(10)⁴

= 0.0215.

Therefore, the decimal expansion will terminate after 4 decimal places.
