Please post the whole question as given to you. Define any variables that would only be obvious to someone versed in astronomy.Homework Statement::Need to solve this equation

Relevant Equations::Mv = - [2.76 (log10(P) - 1.0)] - 4.16

P is = to 7 and I don't know how to get the absolute magnitude please help.

The "relevant equations " section is for standard equations, not any that only relate to the given problem. Maybe that is a standard equation.. I don't know.

And, per forum rules, please show some attempt, or at least provide your thinking so far.

That's a key piece of information right there, that Mv (##M_v##?) is one variable, not two.I just need someone to plug it in and give me Mv

You confused me by saying you needed to solve the equation. What you are asking for is merely to evaluate an expression.

I find it hard to believe there exists any calculator that cannot do this. Just google online calculator and you will find several.

If you mean that you cannot do the whole expression in one hit, just do it in stages.
