WebLet x ≥ 0. Then, by definition, x is the non-negative number whose square is x. The function f ( x) = x is an increasing function. Thus, if p and q are non-negative, then p < q iff p < q. Remark: Regrettably, it is not uncommon in the schools for teachers, and texts, to write, for example, 9 = ± 3. WebNegative Exponent Rule 1: For every number “a” with negative exponents “-n” (i.e.) a -n, take the reciprocal of the base number and multiply the value according to the value of the exponent number. a − n = 1 a n = 1 a × 1 a × … n t i m e s. For example, 4 -3. Here, the base number is 4 and the exponent is -3.
