Logarithm Question!!! Help!!!

Answer 1

solve \[(\log_{10}x)(\log_{10}x^2) + \log_{10} x^3 -5 = 0\]

Answer 2

Are you sure you typed that right? Can you solve it with a graphing calculator? I'm not sure it can be solved without one.

Answer 3

logx(logx^2) + logx^3 - 5 = 0
2(logx)^2 + 3logx - 5 = 0
(2logx + 5)(logx - 1) = 0
solve for x, if 2logx + 5 = 0 or logx - 1 = 0

Answer 4

\[logx^2=2logx\] that's the key...good job RadEn

Answer 5

How do you get from the second step to the third? in RadEn working out

Answer 6

dw i got it

Answer 7

x=10^(-5/2) or = 10 ??
