Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

$3\sqrt{729} ^{2.5}$

write 2.5 as a fraction:

$= 3\sqrt{729} ^{\frac{5}{2}}$

write root 3 as an exponent:

$=729^ {(\frac{1}{3} )(\frac{5}{2} ) }$

Multiply the exponents:

$= 729^\frac{5}{6}$

Rewrite 729 as 3⁶

$=(3^6)^\frac{5}{6}$

Evaluate the exponent:

$=3^5$

Evaluate:

$= 243$
