|
Answer» thank you so much Hii friend!!assume that 5 - 2√3 is rational5- 2√3 = a/b , where a and b are integers .-2 √3 = a/b - 52√3 = 5 - a/b2√3 = (5b - a)/b√3 = )5b - a)/ 2bwe know that a, b , 2 and 5 are integers and they are also rationaltherefore √3 will be rationalbut we know that root 3 is irrationalthere is a contradictionso, 5 - 2√3 is an irrational number |
