For example, the reciprocal of 3 is 1/3. Two numbers are reciprocals (each is the reciprocal of the other) if their product is 1.

Is the sum of two irrational numbers necessarily irrational?

Yes, as long as the two are not mutual resiprocals.

How many 12 W resistors each of the same resistance must be used to produce an equivalent 3.2k ohms 3.0 W resistor if they are connected in parallel?

NOT Possible. In a parallel combination the power tollerence has to increase, thus for every additional resistor in parallel the effective power capacity of the resister would be n(12) Watts where n is the number of resistors connected. ie. if n=3 the power of the combination would rise to 12 x 3 = 36W. Also it is not possible to compute the effective resistance of the combination unless the resitance value of the resitors utilised is known. The question is therefore invalid.
