What is the simplified version of 3\sqrt{135}

Aleonysh [2.5K]

Answer:

The simplified version of $\sqrt[3]{135}$ is $3\sqrt[3]{5}$ .

Step-by-step explanation:

The given expression is

$\sqrt[3]{135}$

According to the property of radical expression.

$\sqrt[n]{x}=(x)^{\frac{1}{n}}$

Using this property we get

$\sqrt[3]{135}=(135)^{\frac{1}{3}}$

$\sqrt[3]{135}=(27\times 5)^{\frac{1}{3}}$

$\sqrt[3]{135}=(3^3\times 5)^{\frac{1}{3}}$

$\sqrt[3]{135}=(3^3)^{\frac{1}{3}}\times (5)^{\frac{1}{3}}$ $[\because (ab)^x=a^xb^x]$

$\sqrt[3]{135}=3\times \sqrt[3]{5}$ $[\because \sqrt[n]{x}=(x)^{\frac{1}{n}}]$

$\sqrt[3]{135}=3\sqrt[3]{5}$

Therefore the simplified version of $\sqrt[3]{135}$ is $3\sqrt[3]{5}$ .

Select the correct answer from each drop-down menu.

RSB [31]

Evidence are simply facts to support a claim, while counterexamples are instances to show the contradictions in a claim

The question is incomplete, as the required drop-down menus are missing. So, I will give a general explanation

To show that a statement is true, you need evidence.

Take for instance:

$\mathbf{if\ a^2 = 4,\ then\ a = 2}$

The evidence that the above proof is true is by taking the squares of both sides of $\mathbf{a = 2}$

$\mathbf{a^2 = 2^2}$

$\mathbf{a^2 = 4}$

However, a counterexample does not need a proof per se.

What a counterexample needs is just an instance or example, to show that:

$\mathbf{if\ a^2 = 4,\ then\ a \ne 2}$

An instance to prove that: $\mathbf{if\ a^2 = 4,\ then\ a = 2}$ is false is:

$\mathbf{a = -2}$

Hence, the complete statement could be:

In a direct proof, evidence is used to support a proof . On the other hand, a counterexample is a single example that shows that a proof is false.
