A is an irrational number b is an irrational number, then ab is an irrational number Root 2 multiplied by root 3, root 6
What about 7/11 times 11/7?
If a+1 is an irrational number, prove that a is an irrational number As the case may be, use the inverse method If a+1 is an irrational number, prove that a is an irrational number As in the case of the inverse method If a+1 is an irrational number, prove that a is an irrational number As in the case of the reverse law
Proving that a is a rational number
1 Is a rational number
A+1 is a rational number (rational number + rational number = rational number)
This contradicts question a+1.
So if it doesn't, then a is an irrational number.
Proving that a is a rational number
1 Is a rational number
A+1 is a rational number (rational number + rational number = rational number)
This contradicts the question a+1, which is irrational.
So if it doesn't, then a is an irrational number.
