Answer:
[tex]-\sqrt{15}[/tex]
Step-by-step explanation:
To put factor back into the square root, we have to put squared value.
like 6 can be written as [tex]\sqrt{36}[/tex] .
Similarly, 5 can be written as [tex]\sqrt{25}[/tex]
= [tex]-5\sqrt{0.6}[/tex]
= [tex]-\sqrt{25*0.6}[/tex]
= [tex]-\sqrt{15}[/tex]
