Not a math question! No links or fake answers!! I will gladly give brainliest! How has social media influenced the marketing and PR activities of companies? Explain in what ways companies, individuals, and NGO'S can impact communities through social media?​

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.

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
