rational, irrational numbers?

Question

need to classify the given numbers as real and rational, real and irrational. or complex.
a. (2)^1/2 +2
b. i
c. 0
d. 3-(-5)^1/2^i
e.(100)^1/5
f. 30007
g. (8)^1/3
h. 4+0i

Answer 1

a. (2)^1/2 +2 [irrational]
b. i [pure imaginary]
c. 0 [real]
d. 3-(-5)^1/2^i [complex]
e.(100)^1/5 [irrational]
f. 30007 [real]
g. (8)^1/3 [real]
h. 4+0i [real]

Answer 2

a. (2)^1/2 +2 - real irrational
b. i - complex
c. 0 - real and rational
d. 3-(-5)^1/2^i complex
e.(100)^1/5 real and irrational
f. 30007 real and rational
g. (8)^1/3 = 2 real and rational
h. 4+0i = 4 real and rational

Answer 3

a. Real & Irrational.
b. Complex.
c. Real & Rational.
d. [3-(-5)^1/2*i = 8. Real & Rational.
e. Real & Irrational.
f. Real & Rational.
g. =2. Real & Rational.
h. Real & Rational.

Answer 4

a) real and irrational
b) complex
c)real and rational
d)complex
e)real and irrational
f)real and rational
g)real and rational
h) complex The number is 4 but you are working with complex numbers because "i" appears

Answer 5

complex are with the i's, so b. d. and h.
Real's are the rest, rational are non repeat or ending, so g. f. and c.
irrational would be a. and e.
