By applying the definition of logarithm, you have

So, if you consider the cubic root of both sides, you have
![x = \sqrt[3]{64} = 4](https://tex.z-dn.net/?f=%20x%20%3D%20%5Csqrt%5B3%5D%7B64%7D%20%3D%204%20)
Answer:
9
Step-by-step explanation:
Substitute w = 3 into the expression
6w - 9
= 6(3) - 9
= 18 - 9
= 9
Answer:
6 ft
Step-by-step explanation:
The surface area of a cube is given by
SA = 6s^2
216 = 6s^2
Divide each side by 6
216/6 = 6s^2/6
36 = s^2
Take the square root of each side
sqrt(36) = sqrt(s^2)
6 =s
Each side is 6ft
