exponents
c^0.5
so 0.5=1/2 and if you have
x^(z/t)=
![\sqrt[t]{x^z}](https://tex.z-dn.net/?f=%20%5Csqrt%5Bt%5D%7Bx%5Ez%7D%20)
so
c^1/2=
![\sqrt[2]{c^1} or \sqrt{c}](https://tex.z-dn.net/?f=%20%5Csqrt%5B2%5D%7Bc%5E1%7D%20or%20%20%5Csqrt%7Bc%7D%20%20)
so

-9 times √c is the answer or more commonly written as
-9√c
Complete question is in comment section :
Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%
According to the empirical rule :
