Step-by-step explanation:

a. 3^9 = 3 × 3 × 3× 3 × 3 × 3 × 3 × 3 × 3

= 27 × 27 × 27 => 19683

b. 3^4 = 3 × 3 × 3 × 3

= 9 × 9 => 81

c. -9² =>  81

d. 9^9 = 9 × 9 ×  9 × 9 × 9 × 9 × 9 × 9 ×  9

= 729 × 729 × 729 =>  387420489

Answer:

Step-by-step explanation:

[tex]\LARGE\begin{gathered}\sf{Evaluate \ All \ Expressions \ First} \\ \sf{ 3^9=19683} \\ \sf{ 3^4=81} \\ \sf{-9^2=81, \ or \ -81, \because} \\ \sf{there's \ a \ difference \ between (-9)^2 \ and \ -(9)^2} \\ \sf{(-9)^2=81 \ and -(9)^2=-81} \\ \sf{ 9^9=387,420,489} \\ \sf{0.81^1=0.81\end{gathered}[/tex]

Now, can you see the expressions that are equivalent?
