Question

- from this equation how many will be ,,b" ?

1= -2b(lg((x+yb)/(ab))

Answer 1

could you clarify the question

Answer 2

b= ?

Answer 3

lg is logarithm on base 10

Answer 4

\[\frac{\log(x+by)}{ab} = -\frac{1}{2b}\]
\[\log(x+by) = -\frac{a}{2}\]
\[x+by = 10^{-a/2}\]
\[b = \frac{10^{-a/2}-x}{y}\]

Answer 5

thank you but there is lg( (x+by)/(ab) )

Answer 6

can you solve it ,help me if there is so ?
