Answer:
[tex]5 \sqrt{3i} [/tex]
Step-by-step explanation:
[tex] \sqrt{ - 108} - \sqrt{ - 3} [/tex]
[tex] \sqrt{ - 1} (108) - \sqrt{ - 3} [/tex]
[tex]i \times \sqrt{108} - \sqrt{ - 3} [/tex]
[tex]i(6 \sqrt{3} ) - \sqrt{ - 3} [/tex]
[tex]6i \sqrt{3} - \sqrt{ - 3} [/tex]
[tex]6i \sqrt{3} - i \sqrt{3} [/tex]
[tex]5 \sqrt{3i} [/tex]
