Use set-builder notation to describe the following sets: (a) {1,2,3,4,5,6,7} (b) {1, 10, 100, 1000, 1} (c) {1,1/2, 1/3, 1/4,1/5, } (d) {0}

A) The set builder notation is: {n | n∈Z, 1≤n≤7}.

B) The set builder notation is:

C) The set builder notation is:

D) The set builder notation can be:

Step-by-step explanation:

Consider the provided information,

We need to use set-builder notation to describe the following sets.

(a) {1,2,3,4,5,6,7}

Here, the number are integer starting from 1 to 7.

Thus, the set builder notation is: {n | n∈Z, 1≤n≤7}.

(b) {1, 10, 100, 1000, 10000}

The above set can be written as:

Thus, the set builder notation is:

(c) {1, 1/2, 1/3, 1/4, 1/5, ...}

Here the numerator is 1 for each term but denominator is natural number.

Thus, the set builder notation is:

(d) {0}

The set builder notation can be:
