[tex] \sqrt[3]{16x^7}\sqrt[3]{12x^9} [/tex]
we can multiply it
[tex] \sqrt[3]{16x^7*12x^9} [/tex]
[tex] \sqrt[3]{16*12x^7*x^9} [/tex]
[tex] \sqrt[3]{4*4*4*3x^{16}} [/tex]
we can simplify it
[tex] 4\sqrt[3]{3x^{16}} [/tex]
[tex] 4x^5\sqrt[3]{3x} [/tex]
we will get
[tex] =4x^5\sqrt[3]{3x} [/tex].............Answer
