Mathematics
1 answer:
Margaret [11]2 years ago
7 0

Answer:

x = 5

Step-by-step explanation:

using the rule of logarithms

log_{b} x = n , then x = b^{n}

given

log_{x} \frac{1}{125} = - 3 , then \frac{1}{125} = x^{-3}

note that \frac{1}{125} = 5^{-3} , so

5^{-3} = x^{-3}

since the exponents are equal, both - 3 then the bases are equal , so

x = 5
