1 answer:
The simplified function of
is ![f(x) = \frac {3^x}4(\sqrt[3]{4})^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%20%7B3%5Ex%7D4%28%5Csqrt%5B3%5D%7B4%7D%29%5Ex)
<h3>How to simplify the base function?</h3>
The function is given as:
![f(x) = \frac 14(\sqrt[3]{108^x})](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%2014%28%5Csqrt%5B3%5D%7B108%5Ex%7D%29)
Expand 108
![f(x) = \frac 14(\sqrt[3]{27 * 4})^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%2014%28%5Csqrt%5B3%5D%7B27%20%2A%204%7D%29%5Ex)
Take the cube root of 27
![f(x) = \frac 14 * 3^x(\sqrt[3]{4})^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%2014%20%2A%203%5Ex%28%5Csqrt%5B3%5D%7B4%7D%29%5Ex)
Evaluate the product
![f(x) = \frac {3^x}4(\sqrt[3]{4})^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%20%7B3%5Ex%7D4%28%5Csqrt%5B3%5D%7B4%7D%29%5Ex)
Hence, the simplified function of
is ![f(x) = \frac {3^x}4(\sqrt[3]{4})^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%20%7B3%5Ex%7D4%28%5Csqrt%5B3%5D%7B4%7D%29%5Ex)

Answer:
63 miles
Step-by-step explanation:
2/70 = 1.8/x Cross multiply
2x = 70 * 1.8 Combine
2x = 126 Divide by 2
x = 126/2
x = 63
The actual distance is 63 miles.
8x^2 = 96x
8x^2 - 96x = 0
8x(x - 12) = 0
8x = 0....x = 0
x - 12 = 0
x = 12
ur number is 12
