    Assuming A2 holds the low value for the range and B2 holds the hi value for the range and assuming that you want 2 to the power of the exponent:
    Code:
    =POWER(2,RAND()*(B2-B1)+B1)
    Only problem is that rand() is called everytime a change is made to the sheet, not sure how to make it call it once per cell
