Answer:
0.216 = 0.6³
Step-by-step explanation:
using the rule of logarithms
• 
x = n ⇔ x = 
0.216 = 3 ⇒ 0.216 = 
<span>We can solve this problem by assigning x as the number of steps were the escalator is standing still. Going up 60 steps means that we must add 60 to x and going down means that we would have to subtract it by x. Since both ways are the same then,
60 + x = 90 - x
x = 15
Therefore, se would have taken 15 steps to either direction.</span>
