[tex]\sqrt{-108}[/tex] - [tex]\sqrt{-3}[/tex]

= [tex]\sqrt{36(3)(-1)}[/tex] - [tex]\sqrt{3(-1)}[/tex]

= 6[tex]\sqrt{3}[/tex] i - [tex]\sqrt{3}[/tex] i

= 5[tex]\sqrt{3}[/tex] i

Answer:

Step-by-step explanation:

√(-108) - √(-3)

= √(-3*36) - √(-3)

= √[(-3)*36] - √(-3)

= √(-3)*(√36 - 1)

= √[(-1)*(3)]*(6-1)

= i*√(3)*(5)

= 5√3i
