Question

Solve the equation logbase27 x = 1 – logbase27 (x – 0.4).

Answer 1

\[\log_{27}x=1-\log_{27}(x-.4) \]

Answer 2

\[\log_{27}x+\log_{27} (x-.4)=1 \]

Answer 3

\[\log_{27}x(x-.4) =1\]

Answer 4

x^2-0.4x=27?

Answer 5

\[27^{1}=x(x-.4)\]

Answer 6

Solve that quadratic equation.

Answer 7

Funny thing is I did all that xD

Answer 8

I got stuck at the quadratic

Answer 9

x^2-.4x=27
10x^2-4x-270=0

Answer 10

\[2(x-5)(5x-27)=0\]

Answer 11

And, of course, if you had trouble factoring, you could always use the quadratic formula.
