Question

7. Write log 10+ 2 log 3 - log 2 as log N.​

Answer 1

log 10+ 2 log 3 - log 2

= log 10 + log (3)^2 - log 2                      [ n log a = log (a)^n ]

= log 10 +log 9 - log 2                             [ log a + log b = log (a.b)]

= log (10.9) - log 2

= log 90 - log 2                                       [ log a - log b = log (a/b)]

= log (90/2)

= log 45

Mark as brainliest if it helped :D
