Negative exponents mean "reciprocal of" and 1/2 as an exponent means square root of. So means "the reciprocal of the square root of 100" or "the square root of the reciprocal of 100" Either way it works out to 1/10.

A more formal way to do this would be to use a property of exponents, , to "separate" the exponent into -1*(1/2):
