$- 2 \sqrt[3]{64 + - 5^{2}}$

Step 1

Replace all occurrences of $+$ $-$ with a single $-$ . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because $1 \cdot - 1 = - 1$

$- 2 \sqrt[3]{64 - 5^{2}}$

Step 2

Raise $5$ to the power of $2$ .

$- 2 \sqrt[3]{64 - 1 \cdot 25}$

Step 3

Multiply $- 1$ by $25$ .

$- 2 \sqrt[3]{64 - 25}$

Step 4

Subtract $25$ from $64$ .

$- 2 \sqrt[3]{39}$

Step 5

The result can be shown in multiple forms.

Exact Form:

$- 2 \sqrt[3]{39}$
