Question

if the value of x² = 2 find the value of x³​

Answer 1

Answer:

x=√2

Step-by-step explanation:

so, x³=(√2)³

x=2√2

is the correct answer

Answer 2

Given: The equation is$x^2=2$.

We have to find the value of$x^3$.

• As we know that a square root of a number is a value, which on multiplication by itself gives the original number.
• And the square root is an inverse method of squaring a number.
• Hence, squares and square roots are related concepts.

We are solving in the following way:

We have,

The equation is$x^2=2$.

So the value of$x$ will be:

$x=\sqrt{2}$

So, the value$x^3$ will be:

$=>x^3\\=>(\sqrt{2} )^3\\\\=>\sqrt{2\times2\times2} \\\\=>\sqrt{2\times 4} \\\\=>2\sqrt{2}$

Hence, the value of$x^3$ is$2\sqrt{2}$.
