Oblicz x jesli a) log x 64=-3 b) log x 27 =3 c) log x 36 = -2 

a)  x^-3=64 [latex]frac{1}{x^3}=64 \ x^3=frac{1}{64} \ x=frac{1}{4}[/latex]   b) [latex]x^3=27 \ x=3[/latex]   c)[latex]x^{-2}=36 \ frac{1}{x^2}=36 \ x^2=frac{1}{36} \ x=frac{1}{6}[/latex]

Witam ,    a) log x 64=-3 x⁻³=64 x= ¼ b)  log x 27 =3 x³=27 x=3 c) log x 36 = -2  x⁻²=36 x= 1/6
