Answer 1

Hey mate ^_^

=======
Answer:
=======

 2 + log a = log 45 - log 2 + log 16 - 2log 3

⇒ 2 + log a = log (45 / 2) + log 16 - log 32

⇒ 2 + log a = log (45 / 2) +  log 16 - log 9

⇒ 2 + log a = log (45 / 2) + log (16 / 9)

⇒ 2 + log a = log [45/2 × 16/9]

⇒ 2 + log a = log 40 

⇒ 2log 10 + log a = log 40

⇒ log 100 + log a = log 40

⇒ log [100 a] = log 40

⇒100 a = 40

⇒ a = 40 / 100 = 0.4
