The diagram shows a cube of side length 3 inches. The points P, Q, and R have the relative location shown. P is one of the vertices of the bottom of the cube, Q is loca te d on an edge and is 1 inch from the top of the cube, and R is located on an edge and is 1 inch from the bottom of the cube: if a plane including the points P, Q, and R cuts through the cube, what is the shape of the resulting cross section?

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.

it is a secret for it not to be compromised sorry
