Question

22.
Show that 5 + 2V7 is an irrational number, where V7 is given to be an
irrational number.
OR​

Answer 1

Step-by-step explanation:

that's a very tedious process.

given we have √7 as irrational, so 2√7 is also irrational because rational x irrational = irrational.

adding a rational to a irrational is also irrational, hence 5 + 2√7 is irrational.
