Help with conversion of equation

Hey guys, I'm trying to convert this equation into terms of y

Q = C (of v) ^n
Q = C (of rho.v) ^ y

v is the veloctiy and rho v is the flow of a material although that doesn't really matter. C is a contant, and rho is equal to 1.42.

When i write of v - i mean if writing it out on paper i would write C with a little v beneath it - the same with rho v.

Dots mean multiplication.

Please help me soon i'm sure i'm being dense but need help!! Also my value for rho might be wrong!

Regards,

M

[tex]Q = C_v ^n[/tex]
[tex]Q = C_v ^ y[/tex]

Solved for y?
Just use logarithms.
 
Whozum -
in the first equation, it is C of v as you wrote
but in the second equation, it is C of rho times v

So logarithms cannot be used can't they?

That doesn't make sense. The subscript is used to identify or elaborate on the variable, it doesn't hold any mathematical informaiton.
 
[tex]Q=C_{\rho*v}^y[/tex]
i agree with whozum. you should just use logarithms. it doesnt matter about the subscript.
