Answer:
4i ,2i√6
Explanation:
√-16
so we know that negatives can be square rooted....
However imaginary numbers exist
and i which is imaginary numbers symbol is equal to
i^2=-1
i= √-1
You can show the number in two parts (imaginary number and real part)
so the 16 is the real part and the -1 is imaginary
so now we can simplfiy the two radicals
√16 x √-1
4 x i
4i
Again
√24 √-1
√4 x √6 x √-1
√4 x √6 x √-1
2 x √6 x i
2i√6
