Solve the equation for x: 2log base 5 of x + log base 5 of 3 = log base 5(1/125)
..
2log5(x)+log5(3)=log5(1/125)=log5(5^-3)=-3 (log of the base^x = x)
log5(3x^2) (exponent and multiplication rules)
Convert to exponential form: (base(5) raised to log of number(-3)=number(3x^2)
5^-3=3x^2
x^2=1/125*3
x=1/(5√5*√3)=1/(5√15)
x=√15/75
