Construct a 4×34×3 matrix A = [ a1 a2 a3 ]
A = [ a→1 a→2 a→3 ] such that {a1,a2}{a→1,a→2} is a linearly dependent set and a 3a→3 is not in the span of {a1,a2}{a→1,a→2}.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
