Let's assume tha 7-2√3 is rational Now, 7-2√3 = a/b (where b is not equal to 0) 2√3 = a+7/b √3. = a+7/2b We can write b in the form √3/b So, if √3 can be written in the form of p/q so it's rational. But it's universal fact tha √3 is irrational "it can not write in form of p/q" Are assumption is wrong that 7-2√3 is rational. Hence, it's not rational than its irrational. Hence, Porved
