Question

Is the expression 9 x 9^9 equivalent to (9x9)^9

Answer 1

Is different

$9X(9^9)=(9x9)^9$

We can match the expressions to see if they give us the same result

Next, try to eliminate expressions to get the same result

$\sqrt[9]{(9\cdot9^9)}=\sqrt[9]{(9\cdot9)^9}$$\begin{gathered} \sqrt[9]{9}\cdot\sqrt[9]{9^9}=(9\cdot9) \\ \sqrt[9]{9}\cdot9=(81) \end{gathered}$
