Nearly any number you can think of is a Real Number. So 8 is a real number.
a real number is a number that can be rational or irrational
If a number is pure imaginary then it has no real component. If it is a real number, then there is no imaginary component. If it has both real and imaginary components, then it is a complex number.
2 is a real number.
Neither.For any whole number there is a real number which is bigger and for any real number there is a whole number which is bigger.
It's a number: 1,000,000,000,000,000,000
A sextillion.
It depends what you mean when you say "plus". If you mean simple addition,the answer is 1,000,000,001,000,000,000,000,000,000(spoken: "1 octillion, 1 pentillion").If you mean what happens when you combine the number of place-values in one-octillion, with the place-values in one-quintillion (i.e., pentillion)? ...which technically is multiplication, not "plus"-ing... then you get:Scientific Notation, American English, British English1045 quattuordecillion septilliard
1 Pentillion
A number of 1 followed by twenty zeroes is one hundred quintillion.
Billion, Trillon ,Quadrillion,Pentillion, Sextillion, Septillion, Octillion, and Nonillion
a pentillion
To get around the confusion between the US and European use of billion (thousand million or million million) and higher numbers new names, based on Greek roots, were proposed. In many countries the European names have now been dropped in favour of the US names. Pentillion was the name proposed for quadrillion = 1015 It would have had 15 zeros if the name had caught on.
The next several in order are: quadrillion, pentillion, hexillion, septillion, octillion. Quadrillion is higher than a trillion!
*Centillion* Is not a measurment but is a number,1 million is 1000,000 Billion-1,000,000,000 Trillion-1,000,000,000,000 Quadrillion-1,000,000,000,000,000 Pentillion-1,000,000,000,000,000,000 Hexillion-1,000,000,000,000,000,000,000 Cept/Heptillion-1,000,000,000,000,000,000,000,000 Octillion-1,000,000,000,000,000,000,000,000,000 Nonillion-1,000,000,000,000,000,000,000,000,000,000 Centillion-1,000,000,000,000,000,000,000,000,000,000,000
The square of a real number is always a real number.
The real number in '101.7' is 101. A real number is a positive whole number.
