Will give medal to the helper :) !! Simplify 2logx-log5=-2
2 log x = log x^2 when you subtract logs you divide the numbers -2 can be expressed as the log of a certain number, use base 10 now what do you have?
not sure
use the info i gave you, take your time
quick question was the 2 outside parentheses or just like you have it with the x only?
just like i have it
ok
i have log (x^2/5) = -2 if Log (base 10) y = -2 what is Y?
y would be 10^-2 = 1/100 do you agree?
yes
so from original log (x^2/5) = log (1/100) so x^2/5 = 1/100 solve for x
how do i do it
i really think it should be (x/5)^2 so that x^2/25 = 1/100 then x^2 = 25/100= 1/4 and x ==/- 1/2
it is supposed to be .223
well it is as written x^2/5 = 1/100 solve for x leave the variable on one side
x^2 = 5/100 =0.05 x=rt 0,05 ==/-0.223
k
any ?
typo == should be =+
