x ![\frac{10}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B7%7D)
Step-by-step explanation:
I’m sure the answer is B < 15
Nanometers are a really small measurement, one billionth of a meter, I believe.
So nanometers is used to describe tiny stuff, like atoms of a water molecule, and waves of light.
Answer:
The simplified expression is:
![\frac{3^9y}{2\times \:81}=\frac{243y}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5E9y%7D%7B2%5Ctimes%20%5C%3A81%7D%3D%5Cfrac%7B243y%7D%7B2%7D)
Step-by-step explanation:
Given the expression
![\frac{3^9\times \:y}{2\times 81}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5E9%5Ctimes%20%5C%3Ay%7D%7B2%5Ctimes%2081%7D)
solving the expression
![\frac{3^9\times \:y}{2\times 81}=\frac{3^9y}{162}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5E9%5Ctimes%20%5C%3Ay%7D%7B2%5Ctimes%2081%7D%3D%5Cfrac%7B3%5E9y%7D%7B162%7D)
∵
∵ ![\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}](https://tex.z-dn.net/?f=%5Cmathrm%7BApply%5C%3Aexponent%5C%3Arule%7D%3A%5Cquad%20%5Cfrac%7Bx%5Ea%7D%7Bx%5Eb%7D%3Dx%5E%7Ba-b%7D)
∵ ![3^5=243](https://tex.z-dn.net/?f=3%5E5%3D243)
Therefore, the simplified expression is:
![\frac{3^9y}{2\times \:81}=\frac{243y}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5E9y%7D%7B2%5Ctimes%20%5C%3A81%7D%3D%5Cfrac%7B243y%7D%7B2%7D)
