I'm assuming the equation is x^3 = 216 or 
(both mean the same thing)
If so, then the solution to x^3 = 216 is x = 6
<span>We can find this by taking the cube root of both sides
</span>x^3 = 216
x = 216^(1/3) .... 1/3 power means cube root
x = 6
Checking the answer:
x^3 = 216
6^3 = 216
6*6*6 = 216
216 = 216
Answer is confirmed
So once again the answer is x = 6. This is assuming the initial assumption made at the top of the problem holds up.

This is something you do through trial and error. Making a list or a table like shown below might help.
Answer:
The mean number of the students who develop hypertension over a life time is 7.8.
Step-by-step explanation:
For each person, there are only two possible outcomes, either they will develop hypertension, or they will not. The probability of a person developing hypertension is independent of any other person, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
Suppose that the probability that a person will develop hypertension over a life time is 60%.
This means that
13 graduating students from the same college are selected at random.
This means that
Find the mean number of the students who develop hypertension over a life time
The mean number of the students who develop hypertension over a life time is 7.8.
