# Why are 4^0 and (-4)^0 is equal to 1,while -4^0 is equal to -1

Answer

4^0 and (-4)^0 both have positive bases, so they equal 1 by the rule stated in step 1. However, -4^0 first requires us to perform the operation inside the parentheses, which makes it -1. Then, we raise -1 to the power of 0, which equals -1. Thus, -4^0 is equal to -1.
