The square root of -108
Elan Coil [88]
Because the number you provided is negative, we won't get a real answer instead a complex answer.

Now simplify the square root.

To simplify a square root, find two factors where one of the factors is a perfect square.

\sqrt{-108} = \sqrt{(-3)(36)} = \sqrt{-3}\sqrt{36} = 6\sqrt{(-1)(3)} = 6\sqrt{(-1)}\sqrt{3} = 6i\sqrt{3}

A girl plants 45 flowers in 30 mins. <br> Determine the unit rate.
notka56 [123]
So 45 in 30mins

we ususlly want to make the smallest number equal to one or as close to one as possible so
45/30=3/3 times 15/10
3/3=1
1 times 15/10=15/10
15/10=5/5 times 3/2
5/5=1
1 times 3/2=3/2
3 divided by 2 is 1.5
1.5 flowers per minute
