Hasil dari (a9/4 : a¾)-5

[tex]a \frac{9}{4} \div a \frac{3}{4} - 5 \\ = \frac{9a}{4} \div \frac{3a}{4} - 5 \\ = \frac{9a}{4} \times \frac{4}{3a} - 5 \\ 3 - 5 = - 2[/tex]

[tex] ({a}^{ \frac{9}{4} } \div {a}^{ \frac{3}{4} })^{ - 5} \\ = ({a}^{ \frac{9}{4} - \frac{3}{4}})^{ - 5} \\ = ({a}^{ \frac{6}{4} } )^{ - 5} \\ = {a}^{ \frac{ - 30}{4} } \\ = \frac{1}{ {a}^{ \frac{30}{4} } } [/tex]
