Answer:
±6i√2
Step-by-step explanation:
Recall that the square root of a negative number is imaginary, which is shown by the use of "i."
Examples: √4 = ±2; √4 = i√4 = ±i2
Then √72 = ±√36√2 = ±6√2, and
√(-72) = ± i√36√2 = ±6i√2
Note that this is identical to the result shown in the problem: √(36·2·(-1) )
Distance between home and school(on map)=5cm
every 4cm=8km
therefore distance between home and school=
5/4×8 = 1.25×8 = 10km
