These numbers are exactly the rational numbers except zero divided by a.Call this set B.. PROOF -- SUFFICIENT. Let q be a rational number other than zero. Then b = q / a is irrational. However, a * b equals a * q … easy equipment rentals beaufort scWebTo say that log 2 3 is rational would mean that there are integers m, n such that log 2 3 = m n. That would imply that 2 m / n = 3, so that 2 m = 3 n. But that says an even number equals an odd number, which is impossible, so log 2 3 cannot be rational. But that doesn't help much in figuring out whether 2 2 log 2 3 is rational. One can write curd orange

"WebSubtraction is just addition of the negative A negative rational is still a rational, and a negative irrational is still irrational. Similarly division is just multiplication by the reciprocal (multiplicative inverse). The reciprocal of a rational is still rational (p/q -> q/p), and the reciprocal of an irrational is still irrational. 1 comment. " - Condition for rational number
