(3√X multipled by 3√X^4)/ X^ -1/3

It is not clear what is rasised to the power of 4   or if the x at the end is raised to -1 or to -1/3

YOU NEED TO USE MORE BRACKETS.

 

$$(3\sqrt X \times 3\sqrt{ X^4})/ X^ {-1/3}$$

 

$$\\(3X^{1/2} \times 3X^2)/ X^ {-1/3}\\\\
=(9X^{1/2} \times X^2)/ X^ {-1/3}\\\\
=9X^{1/2+2-(-1/3)} \\\\
=9X^{(5/2)+(1/3)} \\\\
=9X^{(15/6)+(2/6)} \\\\
=9X^{(17/6)} \\\\$$
