Given
The equation is in the form

Simplify the above equation
To proof
As given in the question the equation is written in the form

By using the exponent property
when you divide powers with the same base you just have to subtract the exponents. i.e

y is not equal to zero.
Now apply this property to the above equation

As

now put this in the above equation
we get

Hence proved
ANSWER
Option D is correct
EXPLANATION
We resolve the forces into component forms.


Also the second is resolved to obtain,


To find the resultant vector, V, We add the corresponding components of the two forces to get:


The correct answer is D.
-10/-16 could be an answer or multiply the same number up and down but the number must be negative
Its b
2854/32 = 1427/16 = 89 3/16
It's the first one. y = 3x
proportional means they are just some multiple of the other.
