You can expand the algebraic expression (x1+2x2+3x3)4 by multiplying 4 to the expression inside the parenthesis. The process is:

4*(x1+2x2+3x3)
= 4*x1 + 4*2x2 + 4*3x3
= 4x1 + 8x2 + 12x3

The final answer is 4x1 + 8x2 + 12x3. I hope it has come to your help.

Use the function below to find F(2). F(t) = 2•1/2^3t

navik [9.2K]

Answer:

$F(2)= \frac{1}{32}$

Step-by-step explanation:

The given function is

$F(t) = 2 \cdot \: \frac{1}{{2}^{3t} }$

To find F(2), we substitute t=2 into the function.

This means that wherever we see t, we put 2

$F(2) = 2 \cdot \: \frac{1}{{2}^{3 \times 2} }$

We multiply the exponent in the denominator to get:

$F(2) = 2 \cdot \: \frac{1}{{2}^{6} }$

We evaluate to get:

$F(2) = 2 \cdot \: \frac{1}{64}$

We now cancel the common factors to get:

$F(2) = \frac{1}{32}$

Use the properties of radicals to simplify the expression

Ludmilka [50]

Given:

The expression is

$\dfrac{\sqrt[3]{9}}{\sqrt[3]{4}}$

To find:

The simplified form of given expression.

Solution:

We have,

$\dfrac{\sqrt[3]{9}}{\sqrt[3]{4}}$

It can be written as

$\dfrac{\sqrt[3]{9}}{\sqrt[3]{4}}=\sqrt[3]{\dfrac{9}{4}}$ $\left[\because \dfrac{\sqrt[a]{x}}{\sqrt[a]{y}}=\sqrt[a]{\dfrac{x}{y}}\right]$

Therefore, the simplified form of given expression is $\sqrt[3]{\dfrac{9}{4}}$ .

Note: We can further simplify this expression but be need use exponential properties.
