Question

Write log 10 + 2 log 3 – log 2 as log N.​

Answer 1

Formulas :

log a + log b = log( ab )

log a - log b = log( a/b )

Step by step explanation:

log 10 + 2 log 3 - log 2

=log 10 + log 3^2 - log 2

=log 10 + log 9 - log 2

=log (10 × 9) - log 2

=log 90 - log 2

=log ( 90 /2 )

= log 45

=log N

Here N = 45
