Evaluate the following exponential expressions.
a. -4²
b. (-2)³
c. (-2)⁴
d. 1000⁰
e. 566¹

 -4² : given
= - (4 * 4) = -16 : expand and calculate

(-2)³ : given
= (-2)*(-2)*(-2) = -8 : expand and calculate

1000⁰ : given
= 1000⁰ = 1 : definition: any nonzero number to the power zero gives 1

566¹ : given
= 566¹ = 566 

(-2)⁴ : given
= (-2)³ × -2 = -8 × -2 = 16
