Question

The set-builder form of the set $\{\frac{1}{16},\frac{1}{32},\frac{1}{64}\}$ is

• A. $\{x:x=\frac{1}{2^n},\text{where}n\in W\text{and}4<n\le 6\}$
• B. $\{x:x=\frac{1}{2^n},\text{where}n\in N\text{and}4\le n\le 6\}$
• C. $\{x:x=\frac{1}{2^n},\text{where}n\in N\text{and}4\le n<6\}$
• D. $\{x:x=\frac{1}{2^n},\text{where}n\in W\text{and}4<n<6\}$

Answer 1

The correct option is B

$\{x:x=\frac{1}{2^n},\text{where}n\in N\text{and}4\le n\le 6\}$

$\{x:x=\frac{1}{2^n},\text{where}n\in N\text{and}4\le n\le 6\}$
