1. ## Two unknowns

p = 1-((0.266)^(0.35*M^(-0.65)))*e^((-0.4)k^1.4)

V = 0.0902(M^(0.7))*(1-e^((-0.32)k^1.8))

There are two equations and the variables both p and v are know.

The unknowns are M and k.

Thank you

2. ## Clarification needed

p = 1-((0.266)^(0.35*M^(-0.65)))*e^((-0.4)k^1.4)

V = 0.0902(M^(0.7))*(1-e^((-0.32)k^1.8))

There are two equations and the variables both p and v are know.

The unknowns are M and k.

Thank you

It looks as though you'll need to take logs if the unknowns are indices, but it's so difficult to read in the format you've given us. Can you clarify this - perhaps re-writing it using LaTeX?

For instance, to write indices like $0.266^{0.35M}$ you'll write $$0.266^{0.35M}$$.
