Answer

Simplifying the expression,

⇒ log 3.6

⇒ log 3610\dfrac{36}{10}

⇒ log 36 - log 10

⇒ log (12 × 3) - log 10

⇒ log 12 + log 3 - log 10

⇒ log (22 × 3) + log 3 - log 10

⇒ log 22 + log 3 + log 3 - log 10

⇒ 2 log 2 + 2 log 3 - 1

⇒ 2 × 0.3010 + 2 × 0.4771 - 1

⇒ 0.6020 + 0.9542 - 1

⇒ 1.5562 - 1

⇒ 0.5562

Hence, log 3.6 = 0.5562
