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
