Given z=k/x^n find k and n if
x is 1 z 100
x is 2 z 25/2
x is 4 z ?
x is ? z 3/25

n = - 3 and k = 100

Step-by-step explanation:

We are given that ......... (1) and we have to find k and n which are constants.

Now, from equation (1), we can write

⇒

Now, for z = 100, x =1 and for z = 25/2, x = 2

Hence,

⇒

⇒ n = - 3

Now, from equation (1) we get

⇒

⇒ k = 100 {Since, x = 1, when z = 100}

Therefore, n = - 3 and k = 100 (Answer)

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
