Answer 2

HEY MATE HERE IS UR ANSWER


IN THE WHOLE MATHS THE NUMBER SYSTEM CONTAINS INFINITES OF NUMBERS . THIS NUMBERS ARE

CATEGORIESED INTO SOME SUB GROUPS .

FOR PRIMARY CLASSES IT WAS TILL RATIONAL NUMBERS . BUT IN EMERGING TO HIGHER CLASSES AN

ANOTHER GROUP OF NUMBER GETS ADDED THATS THE IRRATIONAL NUMBERS .

NOW GOING TOWARDS QUESTION .

AS I TOLD ABOVE THE

IRRATIONAL NUMBERS ARE NUMBERS WHICH IS NOT RATIONAL IE : - THE NUMBERS THAT CANT BE

WRITTEN IN

$\frac{p}{q} \: form$
FOR EXAMPLE

$\: \pi \: \sqrt{2} \: \sqrt{3} ..... \: etc \: are \: all \: irrational \: numbers$

NOW

THE QUESTION WAS WHAT IS REAL NUMBER ??

ANSWER FOR THIS IS THAT

REAL NUMBERS ARE GROUP OF NUMBERS WHICH INCLUDES ALL NUMBER UPTO RATIONAL NUMBERS +

THE NEWLY INTRODUCED IRRATIONAL NUMBERS .

I SAID THAT INCLUDES ALL NUMBERS UPTO RATIONAL NUMBERS BECAUSE RATIONAL NUMBERS

INCLUDES ALL NUMBERS FROM NATURAL NUMBER TO INTEGERS .


SOME EXAMPLES OF REAL NUMBERS ARE

$\pi \: \frac{1}{4} \: \: 0 \: - 2 \: \: 1 \: \sqrt{3} \: etc \: .....$


THEREFORE REAL NUMBERS ARE THE NUMBER GROUP WHICH INCLUDES BOTH RATIONAL AND

IRRATIONAL NUMBERS.


HOPE IT'S HELPFUL.......
