1) Prove or Disporve : For any real numbers \"r\" and \"s\", If\"rs\" is a rational number then both \"r\" and \" s\" are rationalnumbers 1) Prove or Disporve : For any real numbers \"r\" and \"s\", If\"rs\" is a rational number then both \"r\" and \" s\" are rationalnumbers Solution It\'s not true Foe example , if r=2+3 , s=2-3 then rs=4-3=1 ,however , both r and s are irrational numbers.

1) Prove or Disporve : For any real numbers "r" and "s", If"rs" is a rational number then both
"r" and " s" are rationalnumbers
Solution
It's not true Foe example , if r=2+3 , s=2-3 then rs=4-3=1 ,however , both r and s
are irrational numbers
