Question

The sum of two natural number is ? ​

Answer 1

Answer:

NO

Step-by-step explanation:

because,

if 0+0=0

1+(-5)=(-4)

-3+1=(-2)

and there are infinite examples to prove that the sum of 2 numbers can't be a natural number

Answer 2

Given x+y=8

1/x+1/y=8/15

x+y/xy=8/15

From this x+y=15

y=15/x

subsitution of y value in x+y=8

x+15/x=8

$x^{2} + 15 = 8x$

$x ^{2} - 8x + 15 = 0$

$x ^{2} - 3x - 5x + 15 = 0$

$x(x - 3) - 5(x - 3) = 0$

$(x - 5)(x - 3) = 0$

$x = 5or3$

$it \: we \: talk \: value \: of \: x = 5then \: y = 3$

$if \:we \: talk \: value \: of \: x = 3then \: y = 5$

$two \: natural \: no \: are \: 3 \: 5$
