If x3 = 27, what is the value of x?

ipn [44]

Answer:

The value of x is 3

Step-by-step explanation:

Given:

$x^3 = 27$

To Find:

x = ?

Solution:

We Know that

$a = (a^3)^\frac{1}{3}$

$a = (a)^\frac{3}{3}$

We can write 27 as $3 \times 3 \times 3$ = $3^3$

Taking cube root on both sides

$(x^3)^{\frac{1}{3} }= (3^3)^{\frac{1}{3}}$

$x^{\frac{3}{3}} = 3^{\frac{3}{3}}$

$x^1 = 3^1$

x = 3

Alex17521 [72]

9514 1404 393

Answer:

21 1/3 grams

Step-by-step explanation:

The mass is the product of the volume and the density. The volume of a cube is the cube of its edge dimension.

M = Vρ

M = (4 cm)³×(3 g/cm³) = 64/3 g

The mass of the cube is 64/3 = 21 1/3 grams.
