1.

z²=0.02, In the given equation, find whether variables x, y, z etc. represent rational or irrational numbers.

Answer»

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.
