HA2556
Well, OK a multiplier can’t do nonintegral roots “exactly” but
we can get very close. We can approximate nonintegral
roots with equations of the form:

ROOT
This function can be easily built using an HA-2556 and a
potentiometer for easy adjustment as shown in Figures 19
and 20. If a fixed nonintegral power is desired, the circuit
shown in Figure 21 eliminates the need for the output buffer
amp. These circuits approximate the functionV
IN
is the desired nonintegral power or root.
