[tex] = 4[/tex]
Step-by-step explanation:
[tex]( \frac{4 \sqrt{15} }{ \sqrt{15} } ) \\ \\ \frac{4 \sqrt{15} }{ \sqrt{15} } \: \: \: \: cancel \: the \sqrt{15} \: \: and \: \\ then \: \: reduce \: the \: fraction \: \: with \: \sqrt{15} \\ \\ = 4 \\ there \: \: for \: \: we \: \: have \: \: a \: solutions \: \: \\ \\ hope \: \: it \: \: helps \: [/tex]
