Step 1: Understand what '4^0' means. The expression '4^0' means 4 raised to the power of 0.
Step 2: Remember the rule that any non-zero number raised to the power of 0 equals 1. This means that 4, which is a non-zero number, follows this rule.
Step 3: Apply the rule to '4^0'. Since 4 is non-zero, we can say that '4^0' equals 1.
