Answer: 6

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    6-3*n-(-12)=0  

Step  1  :

Pulling out like terms :

Pull out like factors :

18 - 3n  =   -3 • (n - 6)  

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    -3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    n-6 = 0  

Add  6  to both sides of the equation :  

                     n = 6

One solution was found :

                  n = 6

Answer: n = 6

Step-by-step explanation:

6 - 3n = -12

Collect like terms

-3n = -12-6

-3n = -18

Divide both side by -3

-3n/-3 = -18/-3

n = 6

Express (16^3)^1/2 <br> in simplest radical form.
Rufina [12.5K]

Answer:

I assume you mean 16^(1/3) i.e. the cube root of 16

I am also assuming you mean the real cube root because, as you may know, every non-zero real number has three cube root - one real and two complex conjugates.

Since 16 = 8 x 2 and 8 = 2³ then (2³ x 2)^1/3 = (2³)^1/3 x 2^1/3 = 2 x 2^1/3

You might check that the cube root of 16 is about 2.52 which is twice the cube root of 2
