Question

(y-x)³; where x=1, and y=3

Answer 1

Answer:

To find : (y-x)³

Given : x = 1, and y = 3

substituting value of x and y in equation

(y-x)³ = $(3 -1 )^{3}$

         = $2^{3}$

         = 2 x 2 x2

         = 8

Therefore , the value of  (y-x)³ is 8.

Answer 2

According to the given question we have to find the value of

$(y-x)^3$

Given:- $x=1,$ and $y=3$

Now, substitute the given value of x and y as 1 and 3,

So, we will get

$=>(y-x)^3=(3-1)^3$

                   $=(2)^3$

Here, the power of the number 2 is 3, so the number is multiplied by three-time,

$=>(y-x)^3=2\times2 \times 2$

$=>(y-x)^3=8$

Hence, the value of $(y-x)^3$ is $8.$
