a) Exponential expressions have the next form:

where b is the base and x is the exponent. Substituting with b = -8 and x = 3, we get:

b) In this case, the base is -2 and the exponent is 4:

c) In this case, the base is 30 and the exponent is 2:

d) In this case, the base is 0 and the exponent is 100:

Note that when the base is zero, the value of the expression is also zero.
e) In this case, the base is 9 and the exponent is 3:
