Question

log5 x=-1 help me
lgx =-2
log0.01x=-1

Answer 1

$log_5x=-1 \ x=5^{-1} \ x= frac{1}{5}$

$lgx=-2 \ x=10^{-2} \ x= frac{1}{100} \ x=0.01$

$log_{0.01}x=-1 \ x=0.01^{-1} \ x= frac{1}{0.01} \ x=100$

Answer 2

log₅ x=-1    log₅ x=log₅ (5^(-1) )                x=1/5 lgx =-2       lgx =lg (10^(-2) )                    x=1/100
log₀⁾₀₁x=-1  log₀⁾₀₁x=log₀⁾₀₁((1/100)^-1)       x=100
