Question

10. Write the roster form of the set z=[y=1/2u-1:u £N,1<u <4]​

Answer 1

Step-by-step explanation:

Given:-

The set Z = {y = 1/(2u-1) ,u €N, 1<u<4}

To find:-

Write the roster form of the set z=[y=1/2u-1:

u £N,1<u <4]

Solution:-

Given that

1<u< 4 ans u€N

=> u = 2,3

1)Put u = 2 then

y = 1/[(2×2)-1]

y = 1/(4-1)

y = 1/3

2)Put u = 3 then

y = 1/[(2×3)-1]

y = 1/(6-1)

y = 1/5

Z = {1/3 ,1/5}

Answer:-

The roster form of the given set Z = {1/3,1/5}

Used formula:-

Roster form of a set :-

• Writting the each and every element seperating with commas is called roster form or List form of the given set.
