Log Base 8 of 16

What is log base 8 of 16?
log₈(16) = 1.3333
1.3333 is the log base 8 of 16.

Use in Mathematics: Log Base 8 of 16
The below are some of the mathematical applications where log base 8 of 16 can be used:

1. to solve exponential equations where the unknown exponent y satisfies 8^y = 16.
2. to simplify complex multiplication or division operations into addition or subtraction of logarithms.
3. to measure logarithmic scale changes, time complexity of algorithms, and calculus functions.

1. By logarithmic definition, log_b(x) = y means b^y = x. Here, 8^1.3333 = 16.
2. Change of base rule allows converting to natural log (ln) or common log (log₁₀): log₈(16) = ln(16) / ln(8) = log₁₀(16) / log₁₀(8) = 1.3333.
3. Logarithms are defined only for a positive base (b > 0, b ≠ 1) and a positive argument (x > 0).

This step-by-step solution is one of the simple methods to easily understand how to find what is the Log Base 8 of 16, provided along with the use cases of mathematics and real-world problems.

Formula: log₈ 16
log_b(x) = y, if b^y = x

Input:
x = 16
b = 8

step 1 Find the prime factors for 16:
Prime factors of 16 = 8 x 2
log₈(16) = log₈(8 x 2)

step 2 Apply logarithm property of multiplication:
log₈(16) = log₈(8 x 2) = log₈(8) + log₈(2)
= log₈(8) + log₈(2)

step 3 Use the log table to find and apply the log values:
= 1 + 0.3333

step 4 Find the sum:
= 1.3333
log₈(16) = 1.3333
