Answer:

Step-by-step explanation:

log₁₀0.0003 = log₁₀(3 × 10⁻⁴)

= log₁₀3 + log₁₀(10⁻⁴)

= log₁₀3 + (-4)

≈ 0.4771 - 4

= -3.5229

If the value of log₁₀3 is 0.4771. Then the value of the log₁₀0.0003 will be negative 3.5229.

What is a logarithm?

Exponents can also be written as logarithms. A number base logarithm is similar to some other number. It is the exact inverse of the exponent expression.

The logarithm is given below.

log₁₀3 ≅ 0.4771

Then the value of log₁₀0.0003 will be

This can be written as

log₁₀0.0003 = log₁₀ (3 x 10⁻⁴)

We know the property of the logarithm, then we have

log₁₀ (ab) = log₁₀ a + log₁₀ b

log₁₀ aⁿ = n log₁₀ a

log₁₀ 10 = 1

Then we have

log₁₀ (3 x 10⁻⁴) = log₁₀ 3 + log₁₀ 10⁻⁴

log₁₀ (3 x 10⁻⁴) = 0.4771 - 4 log₁₀ 10

log₁₀ (3 x 10⁻⁴) = 0.4771 - 4 x 1

log₁₀ (3 x 10⁻⁴) = 0.4771 - 4

log₁₀ (3 x 10⁻⁴) = -3.5229
