Answer:

3i

Step-by-step explanation:

Square root -9

√(-9) = (3i)(3i)

Note that the "imaginary number" is a non-existent number. Note that in the rules of imaginary numbers: i * i = i² = -1

It is 3i.
The square root of -9 is the square root of -1 times the square root of 9.
So: the square root of 9 is 3, and the square root of -1 is called i (this doesn't actually exist, it's just imaginary).
Then, the square root of -9 is 3i.

Andrew [12]

Answer:she has 120 apples left.

Step-by-step explanation:

Total number of apples that Lexi had in her basket to sell is 300.

If she dropped 122 apples on the ground because she can't use them and sell them, then the number of apples that she has left for sale is

300 - 122 = 178

If then after she sells 58 apples, the number of apples that she has remaining would be

178 - 58 = 120 apples
