Question

Q2.
In the following equations, state whether variables x,y,z etc represent rational or irrational numbers:
1 xsquare=5
II. ysquare=9
III. zsquare=0.04
IV.usquare=17/4
V.vsquare=3
vi. wsquare=27
VII.tsquare=0.4​

Answer 1

Step-by-step explanation:

1.x²=5

so x=plus minus √5

so x represent irrational number

2.y²=9

so y=plus minus 3

so x represent rational number

3.z²=(0.04)

so z=plus minus 0.2

so z represent rational number

4.u²=17/4

so u=plus minus √17/2

u=2.061........

so u represent irrational number

5.v²=3

so v=plus minus √3

v=1.732.......

so v represent irrational number

6.w²=27

so w=plus minus 3√3

w=5.196.......

so w represent irrational number

7.t²=0.4

so t=plus minus √(0.4)

t=0.6324...........

so t represent irrational number
