2 (k - 5) + 3k = k + 6

PolarNik [594]

Answer:

k=4

Step-by-step explanation:

First, distribute the 2 on the left side

2 (k - 5) + 3k = k + 6

2*k +2*-5 +3k=k+6

2k-10+3k=k+6

Combine like terms on the left side

5k-10=k+6

Add 10 on both sides

5k=k+16

Subtract k on both sides

4k=16

Divide by 4 on both sides

k=4

Hope this helps! :)

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.
