Help me please ?????​

Answer 1

Question : find whether they are rational or Irrational.

• 
  `\sqrt{ (2)/(8) }`

• 
  `\sqrt{ (1)/(4) }`

• 
  `(1)/(2)`

• 
  `0.5`

It's a rational number since it can be represented in the fractional format and denominator isn't equal to 0, and it also ends up as a terminating decimal (i.e 0.5).

• 
  `√(2.56)`

• 
  `\sqrt{ (256)/(100) }`

• 
  `(16)/(10)`

• 
  `1.6`

it's also a rational number ( same reason ) cuz it has terminating decimal place and can be represented in fractional format ( where denominator isn't equal to 0)

now just represent them on number line that's it .
