See a solution process below:

The additive inverse (let's call it #a#) is the number added to #8# in this problem which will equal #0#. Or,

#8 + a = 0#

#a = -8#

The additive inverse of #8# is: #-8#

The multiplicative inverse (let's call it #m#) is the number multiplied to #8# in this problem which will equal #1#. Or,

#8 xx m = 0#

#m = 1/8#

The multiplicative inverse of #8# is: #1/8#
