Answer:
32.91
Step-by-step explanation:
[tex] \hookrightarrow \sf \frac{15}{ \sqrt{75} } + \sqrt{108 } + \sqrt{432} [/tex]
[tex] \hookrightarrow \sf \: 19 \sqrt{3} \approx \: 32.908965[/tex]
32.90235
[tex]\frac{15}{\sqrt{75} }[/tex] + [tex]\sqrt{108}[/tex] + [tex]\sqrt{432}[/tex]
= 1.73205 + 10.3923 + 20.784
= 32.90235
