The answer is
![- \frac{1}{6}](https://tex.z-dn.net/?f=-%20%5Cfrac%7B1%7D%7B6%7D%20)
This is because a negative exponent creates a fraction (not a negative number) so 6^-1 becomes 1/6, but the answer is negative because the negative sign is outside the brackets. <span />

<em></em>
<em></em>
<em></em>
Step-by-step explanation:
Given
![Switches = 9](https://tex.z-dn.net/?f=Switches%20%3D%209)
------- on or off
Required
Determine the number of codes to be programmed
Since each switch has any of the on or off controls (i.e on or off), then:
The first switch can be coded in any of the 2 controls
The second switch can be coded in any of the 2 controls
The third switch can be coded in any of the 2 controls
<em>Up till the ninth switch</em>
<em></em>
<em>So, we have that:</em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
Hence, there are 512 possible codes
