How do I write an expression with a negative exponent that has a value between 0 1/2

Something between 0 and 1/2...how about 1/4?
To write this with a negative exponent...
If you have some number with a negative exponent [tex]n^{-x}[/tex], you can rewrite it as [tex]\frac{1}{n^x}[/tex] (and vice versa)
Here's how we work the negative exponent on this one: [tex]\frac14=\frac1{2^2}=\boxed{2^{-2}}[/tex]

For this case, the first thing we must do is define variables.
We have then:
b: base of the expression
n: exponent of the expression (<0)
Writing the expression we have:
[tex]b^n[/tex]
We want a number between 0 and 1/2
Therefore, for b = 2 and n = -2 we have:
[tex]2^{-2}[/tex]
Rewriting the expression:
[tex] \frac{1}{2^2} [/tex]
[tex] \frac{1}{4} [/tex]
[tex]\frac{1}{4}=0.25[/tex]
Answer:
an expression with a negative exponent that has a value between 0 and 1/2 is:
[tex]2^{-2}[/tex]
