Answer:
Answer is 81.
Step-by-step explanation:
Given two expressions are
and ![3^{-\frac{9}{5} }](https://tex.z-dn.net/?f=3%5E%7B-%5Cfrac%7B9%7D%7B5%7D%20%7D)
Now we divide first expression by the second.
![\frac{3^{\frac{11}{5} }}{3^{-\frac{9}{5} } }](https://tex.z-dn.net/?f=%5Cfrac%7B3%5E%7B%5Cfrac%7B11%7D%7B5%7D%20%7D%7D%7B3%5E%7B-%5Cfrac%7B9%7D%7B5%7D%20%7D%20%7D)
![3^{\frac{11}{5}+\frac{9}{5}} = 3^{\frac{20}{5} }=3^{4}=81](https://tex.z-dn.net/?f=3%5E%7B%5Cfrac%7B11%7D%7B5%7D%2B%5Cfrac%7B9%7D%7B5%7D%7D%20%3D%203%5E%7B%5Cfrac%7B20%7D%7B5%7D%20%7D%3D3%5E%7B4%7D%3D81)
Therefore 81 is the answer.
5= 3.966
7=11.949 those are the answers for 5 and 7
A perfect square is what u get when u multiply 2 of the same numbers together.
For example : 2 * 2 = 4.....4 is a perfect square
3 * 3 = 9...9 is a perfect square
4 * 4 = 16....16 is a perfect square
2 cannot be a perfect square because u cant multiply anything by itself that equals 2.
so ur perfect square numbers are : 1,4,9,25,36,81,144,225,400
