Log Base 10 of 10000

What is log base 10 of 10000?
log₁₀(10000) = 4
4 is the log base 10 of 10000.

Use in Mathematics: Log Base 10 of 10000
The below are some of the mathematical applications where log base 10 of 10000 can be used:

1. to solve exponential equations where the unknown exponent y satisfies 10^y = 10000.
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, 10⁴ = 10000.
2. Change of base rule allows converting to natural log (ln) or common log (log₁₀): log₁₀(10000) = ln(10000) / ln(10) = log₁₀(10000) / log₁₀(10) = 4.
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 10 of 10000, provided along with the use cases of mathematics and real-world problems.

Formula: log₁₀ 10000
log_b(x) = y, if b^y = x

Input:
x = 10000
b = 10

step 1 Find the prime factors for 10000:
Express 10000 in terms of base 10: 10000 = 10⁴
log₁₀(10000) = log₁₀(10⁴)

step 2 Apply logarithm property of multiplication/power:
log₁₀(10000) = log₁₀(10⁴) = 4 log₁₀(10)
= 4 log₁₀(10)

step 3 Use the log table to find and apply the log values:
= 4 x 1

step 4 Find the sum:
= 4
log₁₀(10000) = 4
