Question

Log 0.0001=-4 to exponential equation

Answer 1

The original equation log 0.0001 = -4 assumes the base of the logarithm is 10, so the exponential form is 10^ -4 = 0.0001

Answer 2

Since you wrote no base, assume base 10

remember
logₐx=y means a^y=x

so


log₁₀(0.0001)=-4 translates to
10^-4=0.0001
true

exponential equation is
10⁻⁴=0.0001
