Hello! I'm pretty terrible at math and I'm stumped on this question. Could someone please help me? Thank you!

Answer:
[tex]x^{\frac{7}{4} }[/tex]
Step-by-step explanation:
Know: [tex](x^{a})^{b}[/tex] = [tex]x^{ab}[/tex]
---> [tex](x^{\frac{7}{12} } )^{3}[/tex]
---> [tex]x^{\frac{7x3}{12 }[/tex]
---> [tex]x^{\frac{21}{12}}[/tex]
Simplify
---> = [tex]x^{\frac{7}{4}}[/tex]
