If I understand ur question correctly, the first one:
(16x^4)^(1/4) = 2*abs(x)
The answer is 4
So the ratio would be 12/4
Then u simplify into 4/1 ( I divided each number by 4)
Step-by-step explanation:
if I understand this correctly than you are looking for the inverse function of f(x) = y = 3x³.
the inverse function simply tries to calculate the original x it of the original y.
and then, to make it a formal function, we rename x to y and y to x.
y = 3x³
x³ = y/3
![x = \sqrt[3]{ \frac{y}{3} }](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7By%7D%7B3%7D%20%7D%20)
=> as "regular" function
![y = {f}^{ - 1} (x)= \sqrt[3]{ \frac{x}{3} }](https://tex.z-dn.net/?f=y%20%20%3D%20%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7Bx%7D%7B3%7D%20%7D%20)
Answer:
x=6
Step-by-step explanation:
-5(x - 2) = -20
first multiple 5 by x and -2
-5x 10 = -20
subtract 10 from 10 and -20
-5x=-30
then divide 5
x=6
The word format would be forteen point zero five
It could also be said as Forteen and one half
