Question

a + a + a + a\
options: a + 4, 4a, a to the fourth power, 4a + 4

Explanation:

Step1: Analyze the expression

The expression given is \(a + a + a + a\). This represents the sum of four \(a\) terms.

Step2: Simplify the expression

When we add the same variable multiple times, we can use the concept of multiplication as repeated addition. So, adding \(a\) four times is the same as \(4\times a\), which is written as \(4a\).

Answer:

4a (corresponding to the option with "4a" as the text)
