Question

Show that 2√3 + 5 is an irrational number.​

Answer 1

Answer:

therefore it can be written in form of a and b where a and b are co-prime numbers. 5a/b is rational number as it is of the form p/q which is a rational number. but we know that √3 is irrational number so our assumption is wrong. 2√3/5 is irrational.
