Question

Product of a number and its multiplicative inverse is half the number. What is the number

Answer 1

Answer:

For either x=0 and x=2 the product of number and its multiplicative inverse is equal to half of number.

Step-by-step explanation:

Let the number is equal to x.

it is given that product of number and its multiplicative inverse is equal to half of the number, so

x(1/x)=x/2

$x^{2} -2x=0$

so in this either x=0 or x=2.

Hence for either x=0 and x=2 the product of number and its multiplicative inverse is equal to half of number.
