The Key to The LawsAll You Need to Know ...Laws ExplainedThe Law That xmxn = Xm+NThe Law That Xm/Xn = Xm-NThe Law That Xm/N = N√Xm =(N√X )MAnd That Is It!OK, this one is a little more complicated! I suggest you read Fractional Exponentsfirst, so this makes more sense. Anyway, the important idea is that: x1/n = The n-th Root of x And so a fractional exponent like 43/2 is really saying to do a cube (3) and a square root(1/2), in any order. Just remember from fractions that m/n = m × (1/n): The order d...See more on mathsisfun.com OK, this one is a little more complicated!
