If a power has an exponent of zero, it doesn’t matterwhat the base is. The value will be equal to one
When simplifying an expression, we need obey the order ofoperation: BEDMAS
Simplify all “Brackets” first
Then we take it to the exponent.If the exponent is zero, then thevalue now will be equal to one
Next we multiply or divide (from left to right)
Then add or subtract (from left to right)
