Final answer:
The equation log₁₀ 0.00001 = -5 can be written in exponential form as 10^-5 = 0.00001.
Step-by-step explanation:
The equation log₁₀ 0.00001 = -5 can be written in exponential form as 10^-5 = 0.00001. In exponential form, the base is 10 raised to the power of the exponent. Here, the base is 10 and the exponent is -5. Since 10 raised to the power of -5 is equal to 0.00001, option a) 10^-5 = 0.00001 is the correct answer.
