Answer:

The base is: 3 \sqrt[3]{4}

Step-by-step explanation:

Given

f(x) = \frac{1}{4}(\sqrt[3]{108})^x

Required

The base

Expand 108

f(x) = \frac{1}{4}(\sqrt[3]{3^3 * 4})^x

Rewrite the exponent as:

f(x) = \frac{1}{4}(3^3 * 4)^\frac{1}{3}^x

Expand

f(x) = \frac{1}{4}(3^3^\frac{1}{3} * 4^\frac{1}{3})^x

f(x) = \frac{1}{4}(3 * 4^\frac{1}{3})^x

Rewrite as:

f(x) = \frac{1}{4}(3 \sqrt[3]{4})^x

An exponential function has the following form:

f(x)=ab^x

Where

b \to base

By comparison:

b =3 \sqrt[3]{4}

So, the base is: 3 \sqrt[3]{4}

What is the simplified form of i14
cestrela7 [59]

Answer:

-1

Step-by-step explanation:

Rewrite i 14 as ( i 4 ) 3 × i 2 . If i = √ − 1 , then i 2 = − 1 .

From here ( i 2 ) 2 = ( − 1 ) 2 , so i 4 = 1 . If i 4 = 1 ,

then we can say that: i 14 = ( 1 ) 3 × i 2 = i 2 = − 1
