# In the Following Equation, Find Which Variables X, Y, Z Etc. Represent Rational Or Irrational Number: Z2 = 0.04 - Mathematics

In the following equation, find which variables x, y, z etc. represent rational or irrational number:

z2 = 0.04

#### Solution

Given that z2 = 0.04

Now we have to find the value of z

rArr z^24/100

rArr z=sqrt(4/100)

rArrz=2/10

rArrz=1/5

So it is rational number
