The same as for a real number: 1 divided by the number.For example, the multiplicative inverse (or reciprocal) of 2i is 1 / 2i = -(1/2)i.

What are the elements in rational numbers having multiplicative inverse?

All rational numbers, with the exception of zero (0), have a multiplicative inverse. In fact, all real numbers (again, except for zero) have multiplicative inverses, though the inverses of irrational numbers are themselves irrational. Even imaginary numbers have multiplicative inverses (the multiplicative inverse of 5i is -0.2i - as you can see the inverse itself is also imaginary). Even complex numbers (the sum of an imaginary number and a real number) have multiplicative inverses (the inverse of [5i + 2] is [-5i/29 + 2/29] - similar to irrational and imaginary numbers, the inverse of a complex number is itself complex). The onlynumber, in any set of numbers, that does not have a multiplicative inverse is zero.


What is the multiplicative inverse of -0.25?

The multiplicative inverse of a number is the reciprocal of that number. In this case, the multiplicative inverse of -0.25 is -1 / -0.25, which simplifies to -4. This is because multiplying a number by its multiplicative inverse results in a product of 1, the multiplicative identity.


Name the additive inverse and the multiplicative inverse for the number 2.5?

Additive inverse: -2.5 Multiplicative inverse: 0.4


Is the multiplicative inverse of -54 ... 54?

No, the multiplicative inverse of any number is one divide by that number. Stated differently, the product (-54) x (its multiplicative inverse) should be 1. (-54) x (54) is NOT equal to 1.The correct multiplicative inverse is -1/54.No, the multiplicative inverse of any number is one divide by that number.

Multiplicative inverse of a negative number?

The multiplicative inverse is the negative of the reciprocal of the positive value. Thus the multiplicative inverse of -7 is -1/7.

The multiplication inverse of a number is always its?

The multiplicative inverse is also known as the reciprocal. The multiplicative inverse of a number "x" can be expressed as 1/x. In the case of a fraction, exchange numerator and denominator to get the multiplicative inverse.


What is the multiplication inverse of 8?

The multiplicative inverse is when you multiply a certain number, and the product is itself, the number. So, the multiplicative inverse of 8 is of course, 1. For every number, the multiplicative number is 1, because a certain number times 1 is equal to the certain number. It's simple!!


What does the mathematical term ''Multiplicative Inverse'' mean?

The multiplicative inverse of a number (other than zero) is the number such that the product of the two is 1. Thus, the multiplicative inverse of x is 1/x.


What is the multiplication inverse of any number?

The multiplicative inverse of a number is : 1/number i.e., one divided by the number. This doesn't apply to zero. Zero has no multiplicative inverse.


What does mutplicative inverse?

The multiplicative inverse of a number "n", is another number, which you can write as "1/n", defined such that the number, times its multiplicative inverse, is equal to 1.
