Decide whether the following statement is true or false.
{x: x is a letter in the word blurry}
{y: y is a letter in the word blurrier}
Is the statement true or false?

A. The statement is false because not every element of the second set is an element of the first set.

B. The statement is true because at least one of the elements of the first set is an element of the second set.

C. The statement is true because every element of the first set is an element of the second set.

D. The statement is false because not every element of the first set is an element of the second set.

step-by-step explanation:

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 agree because i see the other persons thinking is clear
