 Page Two Here's the rule:  An example: 
The fraction is 'power over root' Another:  The power can be inside or outside the radical signHere's why it makes sense:  (The '2' on the square root is seldom written. We're including it here to make the rule clearer) A few more examples:  Notice that the exponent can be placed outside or inside the radical sign.  Often there is more than one way to do a problem. Look for ways to simplify before using the P/R rule. If the fractional exponent is negative, deal with that first. Decimal exponents can be changed to fractions, so that the P/R rule can be used: 
Here's a handy shortcut when the exponent is negative and the base is a fraction: use the negative in the exponent to flip the base!
