I'm trying to solve an equation where I need to convert from exponential to logarithms in simultaneous equations.
7.5 = a * b^log2(128)
2.5 = a * b^log2(512)
I calculated the log2 in both equation to get this:
7.5 = a * b^7
2.5 = a * b^9
But need to convert to logarithms on both sides to solve for b
Can anyone help please? Thanks in advance

Best ResponseYou've already chosen the best response.0I just divide eq.1 / eq.2 and got 3=b^2 then b=1/9, but I'm not sure if that's ok
