Answer:
A and D
Step-by-step explanation:
A. [tex]4^{\frac{5}{2} } =(\sqrt{4} )^{5}[/tex]
Because:
[tex](\sqrt{4} )^{5} =(4^{\frac{1}{2} } )^{5} =4^{\frac{1}{2}(5) } =4^{\frac{5}{2} }[/tex]
D. [tex]8^{\frac{9}{2} } =(\sqrt{8} )^{9}[/tex]
Because:
[tex](\sqrt{8} )^{9} =(8^{\frac{1}{2} } )^{9} =8^{\frac{1}{2}(9) } =8^{\frac{9}{2} }[/tex]
Hope this helps
