Una esfera para almacenar agua se encuentra sobre una columna a 5m del suelo. ¿Cuánto debe medir una escalera para subir hasta la esfera a darle mantenimiento si su base queda a 3 m de la base de la columna? ¿Cuánto debe medir si colocamos la base de la escalera a 2 m de la columna? ¿Qué ocurrirá con el tamaño de la escalera si duplicamos la altura de la columna? ​

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.

c - they will have the same distribution

this is the only one that could make sense. : )
