Answer:5+3√2
Step-by-step explanation:
GIVEN=√2 IS AN IRRATIONAL NO.
LET US SUPPOSE THAT THE 5+3√2 IS AN RATIONAL NO.
HENCE,
5+3√2=P/Q
3√2=P/Q-5
√2=P/Q-5/3
HENCE √2 IS A. RATIONAL NUMBER
BECAUSE IT IS EQUAL TO THE P BY Q FORM
BUT WE KNOW THAT √2 IS AN IRRATIONAL NO.
HENCE, OUR SUPPOSITION IS WRONG
HENCE 5+3√2 IS AN IRRATIONAL NO
I HOPE IT HELPS YOU
PLZ MARK IT BRAINLESS ANSWER
