evaluate the expression

Question

4z⁰+7

Answer 1

In this expression, the 0 exponent is only applied to the z, so z is 1. Exponents only apply to numbers directly next to them, or parentheses directly next to them- in which case it will apply to everything inside the parentheses.

 

Order of operations : Parentheses Exponents Multiply Divide Add Subtract

 

1. 4(z⁰)+7 ---->  4(1) +7

 

2. Multiply the 4 and 1. So, 4 + 7

 

3. Add. 4+7=11

 

Final answer is 11.
