It is a number which satisfies all the conditions that are given below:
For any three real numbers x, y and z and the operations of addition and multiplication,
• x + y belongs to R (closure under addition)
• (x + y) + z = x + (y + z) (associative property of addition)
• There is an element, 0, in R, such that x + 0 = 0 + x = x (existence of additive identity)
• There is an element, -x, in R, such that x + (-x) = (-x) + x = 0 (existence of additive inverse)
• x + y = y + x (Abelian or commutative property of addition)
• x * y belongs to R (closure under multiplication)
• (x * y) * z = x * (y * z) (associative property of multiplication)
• There is an element, 1, in R, such that x * 1 = 1 * x = x (existence of multiplicative identity)
• For every non-zero x, there is an element, 1/x, in R, such that x * 1/x = 1/x * x = 1 (existence of multiplicative inverse)
• x * (y + z) = x*y + x * z (distributive property of multiplication over addition)
Six is a real number. If you mean "six ninths", yes, that's a real number. If you mean "one ninth", that's also a real number.
What do you mean what is her real number? Her room number is 101! phone
It depends on what you mean by an opposite. Every real number has an additive opposite but 0 does not have a multiplicative opposite.
a number that is not rational real and can be used in an equatuion
It is a real number that can be expressed as a ratio of two integers.

No
It depends on what you mean by an opposite. Every real number has an additive opposite but 0 does not have a multiplicative opposite.

It could be an imaginary number or a complex number or on belonging to a higher class of numbers.

If you mean a whole number then no it would be a decimal number (2.236 recouring)
no
If you mean "real" as in, "does it actually exist as a number", then yes. If you men "real" in the mathematical sense then no. It is two imaginary numbers. ±8i to be exact.
Grrr i need help to know what does it mean to classify a real number and how you do it i have hw due tommorow
2 is 2, by definition. If you mean "what are it's properties?" it is prime, an integer, a real number and rational.
