Answer:
![\frac{1}{81}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B81%7D)
Step-by-step explanation:
<u>Law of exponent</u>
![a^{-m} = \frac{1}{a^{m} }](https://tex.z-dn.net/?f=a%5E%7B-m%7D%20%3D%20%5Cfrac%7B1%7D%7Ba%5E%7Bm%7D%20%7D)
1) Applying the above rule, we have
![9^{-2} = \frac{1}{9^{2} }](https://tex.z-dn.net/?f=9%5E%7B-2%7D%20%3D%20%5Cfrac%7B1%7D%7B9%5E%7B2%7D%20%7D)
= ![\frac{1}{9*9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%2A9%7D)
= ![\frac{1}{81}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B81%7D)
Hey there!
(3^4)^(5) ÷ 3^5
3^4(5)
= 3^20
= 3,486,784,401
3^5
= 3 * 3 * 3 * 3 * 3
= 9 * 9 * 3
= 81 * 3
= 243
= 3,486,784,401 ÷ 243
= 14,348,907
SIMPLIFY IT!
= 14,348,907
≈ 3^15
Therefore, your answer is: 3^15
Good luck on your assignment & enjoy your day!
