What is the Multiplicative Identity for rational numbers?
It is 1, as it is for all complex numbers - which includes real numbers.
Which number is known as the additive identity which number is the multiplicative identity?
Additive identity: zero. Multiplicative identity: one.
What is the multiplicative inverse of a whole number?
Let m be a whole number, then the multiplicative inverse of m is a number n such that mn=1 since 1 is the multiplicative identity. There is only one choice for n, it is 1/m since m(1/m)=1
What is the multiplicative identity for a rational number?
One.
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.
Does the set of rational numbers have multiplicative identity?
Yes. The multiplicative identity for the rational numbers is 1 (also can be written as 1/1).
What is the multicative identity of -3?
-3 does not have a multiplicative identity in the set of real numbers.
What is the multiplicative identity of 2?
The multiplicative identity is a property of a set of numbers, not of an individual number in the set. 1 is the multiplicative identity for the set of all integers, rationals or reals etc. Individual elements of the set do have a multiplicative INVERSE and for 2, this is 1/2 or 0.5
Does the set of rational numbers have a multiplicative identity?
Yes, it is 1.
What is the Multiplicative Identity for rational numbers?
It is 1, as it is for all complex numbers - which includes real numbers.
What is called the multiplicative identity for whole numbers and why is it called this?
The multiplicative identity is the number 1. Why? Because if you multiply (or divide) a number by 1, it remains the same. eg a x 1 = a In a similar manner, the additive identity is 0. If you add (or subtract) 0 from a number, it remains the same eg a + 0 = a.
Which number is known as the additive identity which number is the multiplicative identity?
Additive identity: zero. Multiplicative identity: one.
What is the definition of multiplicative inverse?
In a set S, the multiplicative inverse of a non-zero element x is an element of the set, y, such that x*y = y*x = i, the identity element of S. For the set of numbers, the multiplicative identity is 1 and the multiplicative identity is also denoted by 1/x or x^-1.
What property would 17x1 equals 17 be?
The fact that 1 is the multiplicative identity for numbers.
When you multiply a number and 1 the product is that number?
Yes. 1 is the multiplicative identity for numbers.
Why is one called the multiplicative identity?
why is one called the multiplicative identity
What is the math property of 1m equals m?
It is the property that 1 is the multiplicative identity for sets of numbers.
