Question 544868: please help me solve this equation 2log x - log 5 = log 125
Answer by saifoo.khan(162)   (Show Source):
You can put this solution on YOUR website! 2log x - log 5 = log 125
log x^2 - log 5 = log 125
lg( x^2/5) = lg 125
x^2/5 = 125
x^2 = 125*5
x^2 = 626
taking square root on both sides,
x = sqrt(625)
x = 25
answer. =)
