Answer:
A
Step-by-step explanation:
Given
[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
