Question

Solve the equation for the unknown variable.

Answer 1

Answer:

d = -3

Step-by-step explanation:

Given the equation:

$d^3 = -27$

Solve for d:

Take both sides cube root we have;

$d =\sqrt[3]{-27}$

We can write 27 as:

$27 = 3 \cdot 3 \cdot 3 = 3^3$

then;

$d = \sqrt[3]{-3^3}$

Using the rules:

$\sqrt[n]{a^n} = a$

$\sqrt[3]{-1} = -1$

then;

$d = -\sqrt[3]{3^3} = -3$

therefore, the unknown variable d is, -3
