Chapter 1: Q36. (page 15)

Use the properties of real to answer each question
If $m + n = m$ , what is the value of $n$ ?

Short Answer

Expert verified

Value of $n$ is 0.

Step by step solution

- Write properties of real numbers

Properties of real numbers are written in following table:

For any real numbers $a, b,$ and $c :$
Property	Addition	Multiplication
Commutative	$a + b = b + a$	$a 路 b = b 路 a$
Associative	$(a + b) + c = a + (b + c)$	$(a 路 b) 路 c = a 路 (b 路 c)$
Identity	$a + 0 = a = 0 + a$	$a 鈰� 1 = a = 1 鈰� a$
Inverse	$a + (- a) = 0 = (- a) + a$	If $a 鈮� 0$ , then $a 路 \frac{1}{a} = 1 = \frac{1}{a} 路 a$
Distributive	$a (b + c) = a b + a c and (b + c) a = b a + c a$

- Compare with given equation

Compare identity property of addition with given equation to find required value as shown below

$\begin{matrix} a + 0 = a \\ m + n = m \end{matrix}$

Thus, on substituting 0 for n, given equation is satisfied.

- Verification

Substitute 0 for n in given equation

$\begin{matrix} m + n = m \\ m + 0 = m \\ m = m (T r u e) \end{matrix}$

Thus, value of n is 0.
