Question

It is given that y is directly proportional to x^n.
Write down the value of n when
(i) y mạ is the area of a square of length x m,
(ii) y cm is the volume of a cube of length x cm.​

Answer 1

area of square = x^2

so here n = 2

volume of cube = x^3

so here n = 3

hope it helps....

Answer 2

Answer:

In first part ans is n=2. In second part ans is n=3

Step-by-step explanation:

Given That y is directly proportional to x's power n.

1)Area of square =L's square

So y= x's spuare

X2 = Xn

So x cancel with each other and n=2

2) Area of cube=l3

So, y = x3

X3= Xn

Again x cancel with each other and n= 3
