Step-by-step explanation:
Given,
1. The given expression is
.
We need to write it into exponential form.
We know that,
![\sqrt[a]{x} =x^{1/a}](https://tex.z-dn.net/?f=%5Csqrt%5Ba%5D%7Bx%7D%20%3Dx%5E%7B1%2Fa%7D)
Here, a = 10
So,
![\sqrt[10]{x^9}=(x^9)^{1/10}\\\\=x^{9\times \dfrac{1}{10}}\\\\=x^{9/10}\\\\=x^{0.1}](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7Bx%5E9%7D%3D%28x%5E9%29%5E%7B1%2F10%7D%5C%5C%5C%5C%3Dx%5E%7B9%5Ctimes%20%5Cdfrac%7B1%7D%7B10%7D%7D%5C%5C%5C%5C%3Dx%5E%7B9%2F10%7D%5C%5C%5C%5C%3Dx%5E%7B0.1%7D)
2.
![(\sqrt[4]{3y} )^3\\\\=((3y)^3)^{1/4}\\\\=3^{3\times \dfrac{1}{4}}\times y^{3\times \dfrac{1}{4}}\\\\=3^{3/4}y^{3/4}](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B3y%7D%20%29%5E3%5C%5C%5C%5C%3D%28%283y%29%5E3%29%5E%7B1%2F4%7D%5C%5C%5C%5C%3D3%5E%7B3%5Ctimes%20%5Cdfrac%7B1%7D%7B4%7D%7D%5Ctimes%20y%5E%7B3%5Ctimes%20%5Cdfrac%7B1%7D%7B4%7D%7D%5C%5C%5C%5C%3D3%5E%7B3%2F4%7Dy%5E%7B3%2F4%7D)
Hence, this is the required solution.
Since the tax is 6% and 6% of 3.60 is .216, you just round the .216 to .22 and add that to 3.60 to get your final price as $3.88.
