Question

now, multiply.
$2^3 + 20 = 2 \cdot 2 \cdot 2 + 20$
$= \square + 20$

Explanation:

Step1: Calculate \(2^3\)

\(2^3\) means \(2\times2\times2\). Let's compute that: \(2\times2 = 4\), then \(4\times2 = 8\). So \(2^3 = 8\), which is the same as \(2\cdot2\cdot2 = 8\).

Step2: Substitute the value

Now we substitute \(2\cdot2\cdot2\) with its value, which is 8. So the expression becomes \(8 + 20\), and the blank should be filled with 8.

Answer:

8
