this is hard i need help

Answer:
a. 6
b. -2
Step-by-step explanation:
a. you take the cube root of 216 to get 6. 6x6x6=216
b. multiply both sides of the equation by -4 to get n^3= -8
write in exponential form to get n^3= -2^3
take the root of both sides of the equation
n= -2
Hope this helps
Answer:
1) 6 x 6= 36 x 6 = 216
x=6
2) - 1/4 x -8 = 2
cube root of -8 is -2
n= -2
