Two alternatives...
* Transcript crShow: 1 asString, String tab, 2 asString.
* Transcript crShow: 1 ; tab ; show: 2.

btw, just some general feedback on your code. Since b is set to 1 before 
the loop and at the end of the loop, it is equivalent to just do that at 
the start of the loop instead (unless you are relying on b=1 after the 
loop. And here is an alternative...
0 to: 9 do: [     :a |
    b := 1.
    a timesRepeat: [b := b*2].
    Transcript show: '2^a = '.
    Transcript show: b ;cr.
].
