Answer:
Option #1: 
Step-by-step explanation:
#1: Multiply
and
:
![\frac{\sqrt[3]{6}}{\sqrt[4]{6}} * \frac{\sqrt[3]{6}}{\sqrt[4]{6}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B6%7D%7D%7B%5Csqrt%5B4%5D%7B6%7D%7D%20%2A%20%5Cfrac%7B%5Csqrt%5B3%5D%7B6%7D%7D%7B%5Csqrt%5B4%5D%7B6%7D%7D)
#2: Combine and simplify the denominator:
<u>- </u><u>Multiply </u>
<u>by </u>
= ![\frac{\sqrt[3]{6} \sqrt[4]{6}^{3} }{\sqrt[4]{6} \sqrt[4]{6}^3}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B6%7D%20%20%5Csqrt%5B4%5D%7B6%7D%5E%7B3%7D%20%7D%7B%5Csqrt%5B4%5D%7B6%7D%20%5Csqrt%5B4%5D%7B6%7D%5E3%7D)
<u>- Raise </u>
<u> to the power of 1</u>
<u>- Use the power rule </u>
<u> to combine exponents:</u> ![\frac{\sqrt[3]{6} \sqrt[4]{6}^{3} }{\sqrt[4]{6}^{1+3}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B6%7D%20%5Csqrt%5B4%5D%7B6%7D%5E%7B3%7D%20%7D%7B%5Csqrt%5B4%5D%7B6%7D%5E%7B1%2B3%7D%7D)
<u>- Add 1 and 3</u>
<u>- Rewrite </u>
<u>as 6:</u> ![\frac{\sqrt[3]{6} \sqrt[4]{6}^3}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B6%7D%20%5Csqrt%5B4%5D%7B6%7D%5E3%7D%7B6%7D)
#3: Simplify the numerator:
<u>- Rewrite the expression using the least common index of 12:</u> ![\frac{\sqrt[12]{6^4} \sqrt[12]{216^3}}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B12%5D%7B6%5E4%7D%20%5Csqrt%5B12%5D%7B216%5E3%7D%7D%7B6%7D)
<u>- Combine using the product rule for radicals:</u> ![\frac{\sqrt[3]{6^4 *216^3}}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B6%5E4%20%2A216%5E3%7D%7D%7B6%7D)
<u>- Rewrite 216 as </u>
<u>:</u> ![\frac{\sqrt[3]{6^{4}*(6^{3})^{3}}}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B6%5E%7B4%7D%2A%286%5E%7B3%7D%29%5E%7B3%7D%7D%7D%7B6%7D)
<u>- Multiply the exponents in </u>
<u>:</u> ![\frac{\sqrt[12]{6^{4}*6^{9}}}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B12%5D%7B6%5E%7B4%7D%2A6%5E%7B9%7D%7D%7D%7B6%7D)
<u>- Use the power rule</u>
<u>to combine exponents and add </u>
<u>:</u>
![\frac{\sqrt[12]{6^{13}}}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B12%5D%7B6%5E%7B13%7D%7D%7D%7B6%7D)
<u>- Raise 6 to the power of 16:</u> ![\frac{\sqrt[12]{13060694016}}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B12%5D%7B13060694016%7D%7D%7B6%7D)
<u>- Rewrite 13060694016 as</u>
<u>:</u> ![\frac{\sqrt[12]{6^{12}*6}}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B12%5D%7B6%5E%7B12%7D%2A6%7D%7D%7B6%7D)
<u>- Pull terms out from under the radical:</u> ![\frac{6\sqrt[12]{6}}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B6%5Csqrt%5B12%5D%7B6%7D%7D%7B6%7D)
#4: Cancel the common factor of 6:
![\frac{\sqrt[12]{6}}{6}=6\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B12%5D%7B6%7D%7D%7B6%7D%3D6%5Cfrac%7B1%7D%7B2%7D)
<u>The correct simplified answer for </u>
<u>is Option #1:</u>
