Find the multiplicative inverse (i.e., reciprocal) of:
(i)
(ii)
(iii)
(iv)
(v)
(vi)
(vii)
(viii)
(ix)
(x)
A multiplicative inverse for a number x, is a number which when multiplied by x yields the multiplicative identity, 1
The multiplicative inverse of a rational number 
is
.
Therefore,
(i) The multiplicative inverse of 
=
.
(ii) The multiplicative inverse of 
=
.
In standard form,
(iii) The multiplicative inverse of 
=
.
In standard form,
.
(iv) The multiplicative inverse of 
=
.
(v) The multiplicative inverse of 
=
.
(vi) The multiplicative inverse of 
=
.
In standard form,
(vii) The multiplicative inverse of -1 =-1.
(viii) The multiplicative inverse of 
is undefined.
Since, 
is undefined.
(ix) The multiplicative inverse of 
=
.
(x) The multiplicative inverse of 
=
.
In standard form,
