Hey there!
Assume that "[tex]81 [/tex]" would be [tex]3^4[/tex] because that's what it is equal to in exponential form
So, now we get this as our new problem!
[tex](3^4)^ \frac{5}{4} [/tex]
The new problem gave us the outcome of: [tex]3^5 [/tex]
[tex]3^5 = 243 [/tex]
Answer: [tex]3^5 = 243 [/tex]
Good luck on your assignment and enjoy your day!
