to state an irrational number

Asked by vskksv | 12th Mar, 2008, 10:44: AM

Expert Answer:

let 6+ 2 be rational,

this implies ( 6+ 2)^2 is rational.

so, 6+2+2 12 is rational

this implies 8+2 12 is rational.

but 12 is irrational. this implies 2 12 is irrational

therefore, 8+2 12 is irrational.

so our assumption is wrong.

hence, 6+2 is a irational number .
