Question

Which equation shows a valid step in solving:

Answer 1

Answer:

The equation $(\sqrt[3]{2x-6})^3=(-\sqrt[3]{2x+6})^3$ represents the valid step in solving the given expression $\sqrt[3]{2x-6}+\sqrt[3]{2x+6}$

Therefore the option $(\sqrt[3]{2x-6})^3=(-\sqrt[3]{2x+6})^3$

Step-by-step explanation:

Given expression is $\sqrt[3]{2x-6}+\sqrt[3]{2x+6}$

To solve the given expression as below :

$\sqrt[3]{2x-6}+\sqrt[3]{2x+6}$

$\sqrt[3]{2x-6}=-\sqrt[3]{2x+6}$

cubing on both sides we get

$(\sqrt[3]{2x-6})^3=(-\sqrt[3]{2x+6})^3$

The equation $(\sqrt[3]{2x-6})^3=(-\sqrt[3]{2x+6})^3$ represents the valid step in solving the given expression $\sqrt[3]{2x-6}+\sqrt[3]{2x+6}$

Therefore the option $(\sqrt[3]{2x-6})^3=(-\sqrt[3]{2x+6})^3$
