Fractional Exponents vs Radicals

Use of radicals may sometimes be avoided by substituting a fractional exponent:

(a2b2)1/2instead ofa2b2.

As with unstacking fractions, if clarity is sacrificed by making the equation fit within the text, it is preferable to set it off. For example, E = 1.96 {[P (1 − P)]/m}1/2 fits within the text, but the centered


might be more easily understood.
