Z² = 0.02
0.02 can be written as 2 / 100
=> Z² = 2 / 100
=> Z = √ ( 2 / 100 )
=> Z = + √2 / 10, - √2 / 10
Since √2 is an irrational number, √2 / 10 is an irrational number.
Therefore, Z is also an irrational number.

Given z² = 0.02
=> z = ± √0.02
=> z = ± √(2/100)
=> z = ± √2/10
Therefore ,
Here , variable z is an irrational
number.
