Is different
[tex]9X(9^9)=(9x9)^9[/tex]We can match the expressions to see if they give us the same result
Next, try to eliminate expressions to get the same result
[tex]\sqrt[9]{(9\cdot9^9)}=\sqrt[9]{(9\cdot9)^9}[/tex][tex]\begin{gathered} \sqrt[9]{9}\cdot\sqrt[9]{9^9}=(9\cdot9) \\ \sqrt[9]{9}\cdot9=(81) \end{gathered}[/tex]
