What is 3n to the power of 2 divided by n to the power of 3 equal to

91.125

Step-by-step explanation:

3n X 3n  = 9n squared

9n squared divided by 2n = 4.5n

4.5n X 4.5n X 4.5n = 91.125

probability for j is 1/4

while

a is 1/6

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
