Answer:
Step-by-step explanation:
![\huge \sqrt[3]{9 {x}^{4} } . \sqrt[3]{3 {x}^{8} } \\ \\ \huge = \sqrt[3]{9 {x}^{4} \times 3 {x}^{8} } \\ \\\huge = \sqrt[3]{27 {x}^{12} } \\ \\ \huge\orange{= 3 {x}^{4} }](https://tex.z-dn.net/?f=%5Chuge%20%5Csqrt%5B3%5D%7B9%20%7Bx%7D%5E%7B4%7D%20%7D%20.%20%20%5Csqrt%5B3%5D%7B3%20%7Bx%7D%5E%7B8%7D%20%7D%20%20%5C%5C%20%20%5C%5C%20%5Chuge%20%3D%20%20%5Csqrt%5B3%5D%7B9%20%7Bx%7D%5E%7B4%7D%20%5Ctimes%203%20%7Bx%7D%5E%7B8%7D%20%20%7D%20%20%5C%5C%20%20%5C%5C%5Chuge%20%20%3D%20%20%5Csqrt%5B3%5D%7B27%20%7Bx%7D%5E%7B12%7D%20%20%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Chuge%5Corange%7B%3D%203%20%7Bx%7D%5E%7B4%7D%20%7D)
So lets add the common fractions 3/4+3/4+1/4+1/2=7/4+1/2=18/8, now the whole numbers 3+1+2+4+2=12, so 12 18/8 and simplify 14 2/8= 14 1/4 <span />
