La compañía Aero&Fly solicitó carteles de publicidad aérea, cuyas dimensiones son 15 m de largo por 8.5 m de ancho. También requieren promocionar sus viajes mediante publicidad en bardas, y por recomendación de su editor decidieron colocar anuncios cuyas medidas son 1 quinto del tamaño de los carteles aéreos. ¿Cuánto miden de largo y ancho las bardas?

false

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.

x=0
