Question
What is the multiplicative inverse of ?10−3(a) 100 (b) -100 (c) (d) 1000
Solution
The multiplicative inverse of a number is the number that, when multiplied by the original number, gives the product as 1.
The multiplicative inverse of a number 'x' is given by 1/x.
So, the multiplicative inverse of -10^(-3) is 1/(-10^(-3)).
Solving this, we get -10^3, which is -1000.
So, the multiplicative inverse of -10^(-3) is -1000.
Therefore, the correct option is (c) -1000.
