Why are lines e and c skew lines?
a. they lie in different planes and will never intersect.
b. they lie in the same plane but will never intersect.
c. they lie in different planes but will intersect if a plane is drawn to contain both lines.
d. they lie in different planes and will be parallel if a plane is drawn to contain both lines.

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.

i use my brain for prombles like this maybe you could try it
