Question

If x3 = 125, find x²

Answer 1

The value of $x^{2}$ is 25 when we have (cube of x = 125) $x^{3}$ = 125.

According to the question,

We have the following expression:

$x^{3} = 125$

Now, we will do the cube roots on both the sides:

$\sqrt[3]{x^{3} } = \sqrt[3]{125}$

(We can find the cube roots of 125 by finding the Least Common Multiple or LCM.)

So, we will have the following expression:

x = 5

Now, to find the value of $x^{2}$, square on both the sides:

$x^{2} = 5^{2}$

$x^{2}$ = 25

(More to know: when we square a number we multiply a number two times and when we find cube of a number then we multiply a number three times.)

Hence, the value of $x^{2}$ is 25.
