Simplify the foll

Class 9th Tamilnadu Board Math Term-III 2. Scientific notations of real numbers and logarithms

Answer :

⇒ log₈(16×52) - log₈13

(∵ log_a(M×N) = (log_aM) + (log_aN) and )

⇒

(∵ loga(M ÷ N) = (log_aM) - (log_aN))

⇒ log₈(16×4) = log₈64

⇒ 8x = 64 or x = 2

(∵ a^x = b is the exponential form of logarithmic form of log_ab)
