2 is a real number.
Yes, square of 2 is a real number. Real numbers fall into 2 categories, Rational and Irrational. Square of 2 is an irrational number.
No. 2 is a real number, whole number, and rational number.
A real number dosen't have to be a rational number as a real number can be rational or irrational i.e the root of 2 is irrational and real. So is (pi).
2 is a real world prime number.
The short answer is "Nothing". In the complex domain, the number of nth roots of any real number is n. Every non-negative real number has 2 square roots. Every real number has 3 cube roots. Every non-negative real number has 2 real square roots and 2 imaginary ones. and so on. So what?
3 all positive, whole numbers are real
The square of a real number is always positive no matter which real number you start with. Therefore, a negative number squared is positive. For example: 2 * 2 = 4, -2 * -2 = 4.
The number 4 is an integer (the Number 4.1 is a real number and not an integer) The number 2 is an integer (the number 2.9 is a real number and not an integer) 4-2 = 2 4+2 = 6 The above are examples of how the integers 4 and 2 can be added or subtracted.
There is no first real number. If x laid claim to being the smallest real number, then x/2 would have a better claim. And so on.
Basically 1, 2, 3, 4, 5 are all real numbers, but as a real number doesn't only limit of integers, it can be 2/5, √2, or even π.
Yes.
