even number -yes

positive number -yes

negative number -no

rational number -yes

irrational number - no

imaginary number - no

real number - yes

natural number - yes

counting number - yes

transcendental # - no

Answer 2

It's a even, positive, irrational,  and real number

Answer 3

root 16 is 4

so ya

just do it for that

Answer 4

root 16 = 4, -4   (because 4^2 = 16 and (-4)^2 = 16)

+4/-4

integer: yes, integers include negative whole numbers, 0 and positive whole numbers. { ... -4,-3,-2,-1,0,1,2,3,4,..}

digit: yes ? A digit is defined as a symbol used in numerals to represent numbers. A numeral is a sequence of digits.

even number: yes {2,4,6,8 ...

positive: +4 yes, -4 no

negative: -4 yes, +4 no

rational: yes, include fractions and decimals that terminate or repeat.

irrational: no, irrational #'s are fractions that do not terminate or repeat (ex: pi)

imaginary: no, imaginary #'s are complex #'s and include "i" (ex: root -16 = 4i)

real: yes, everything without an "i" is real.

natural: yes, includes whole numbers beginning with 1...

counting: yes, a counting number is any number that you

can use to count something ... doesn't include zero, negatives, fractions or decimals.

transcendental:no, a transcendental number is a complex number that is not algebraic (it does not arise through an algebraic expression such as root -16. 4i would be a transcendental complex number.

* Don't forget whole #'s : natural and zero

Thanks, I learned a few definitions myself.
