Answer:

16√3
-45+15i
√255
6√2 +3√10

Step-by-step explanation:

$-4i\sqrt{-48}=-4i\sqrt{(-1)(4^2)(3)}=(-4i)(4i)\sqrt{3}=16\sqrt{3}$

$(-5-5i)(3-6i)=-5(3-6i)-5i(3-6i)=-15+30i-15i+30i^2=-15-30+15i\\\\=-45+15i$

$\sqrt{3}\sqrt{5}\sqrt{17}=\sqrt{3\cdot 5\cdot 17}=\sqrt{255}$

$\sqrt{3}(\sqrt{24}+\sqrt{30})=\sqrt{3\cdot 24}+\sqrt{3\cdot 30}=\sqrt{6^2\cdot 2}+\sqrt{3^2\cdot 10}\\\\=6\sqrt{2}+3\sqrt{10}$

The applicable identities are ...

$\sqrt{a^2b}=a\sqrt{b}\\\\i^2=-1$

Mumz [18]

Assign x as the number of females.

Since makes are six times more: 6x is the male variable.

In total there are 7x students.

So the fraction for males is : 6/7

There's no way to simplify further because there's no term common to both the denominator/numerator.

Answer: 6/7
