A tree farm, located on a rectangular landmass, currently has 56,293 trees on it. At opposite corners of the farm, there are check- in stations 12 miles apart, as shown below.

If a measures 60°, what is the approximate density of trees on the farm?
OA.
452 trees per square mile
ОВ.
903 trees per square mile
OC.
62 trees per square mile
OD
782 trees per square mile

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
