Question

if log 10 + 2 log 3 - log b is equals to login then find n​

Answer 1

Answer:

90/b

Step-by-step explanation:

Answer 2

Answer:

$here \: \: log(10) + 2 log(3) - log(b ) = log(n) \\ log(10 ) + log( { {3}^{2} } ) - log(b) = log(n) \\ log(10) + log(9) - log(b) = log(n) \\ log(10 \times 9) - log(b) = log(n) \\ log( \frac{90}{b} ) = log(n) \\ n = \frac{90}{b \:} \: ans.$
