Lemma 2.3.2 (Multiplication is commutative). Let n,m be natural питbers. hen n x m = mхп.

Paraphin [41]

Answer:

Multiplication is commutative.

Step-by-step explanation:

Let n,m be two natural numbers.

We have to show that $n\times m=m\times n$

We will prove this by induction

For n = 1, we have $n\times 1 = 1\times n = n$ , which is true.

Let the given statement be true for n-1 natural numbers, that is,

$(n-1)\times m = m\times (n-1)$

Now, we have to show that it is true for n natural numbers.

$nm = (n-1)m + m = m(n-1) + m$

which is equal to

$(m-1)(n-1) + (n-1) + m$

$= (m-1)(n-1) + (m-1) + n$

$= n(m-1) + n$

$= (m-1)n + n$

$= mn$

Hence, by principal of mathematical induction, the given statement is true for all natural numbers.

Hi Math do please I don’t want fail :(

NeX [460]

Answer:

Step-by-step explanation:

(2 , 1) ; ( 3 , 2)

$Slope =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{2-1}{3-2} =\dfrac{1}{1}\\\\=1$

Equation of line: y = mx +b

y = 1x + b

Plugin x = 2 and y = 1 in the above equation

1 = 2 + b

1- 2 = b

b = -1

y = 1x - 1
