What is the relationship between the total number of bottle caps Diego has collected after each month and the total number of bottle caps Carlos has collected after each month? Use the table to answer the question. Use the drop-down menu to show your answer. Number of Bottle Caps Collected Month Carlos Diego 1 7 28 2 14 56 3 21 84 4 28 112 5 35 140 The total number of bottle caps Diego has collected is always Choose... the total number of bottle caps Carlos has collected.

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.
