Question 684196

Can you help me solve. I'm having problems using the laws. thanks in advance.
Log2t^3-Logt = Log16+Logt


{{{log (2t^3) - log t = log 16 + log t}}}


{{{log ((2t^3)/t) = log 16t}}}


{{{(2t^3)/t = 16t}}}


{{{2t^3 = 16t^2}}} ------ Cross-multiplying


{{{2t^3 - 16t^2 = 0}}}


{{{2t^2(t - 8) = 0}}}


{{{highlight_green(t = 8)}}}		OR		t = 0 (ignore as log of a number CANNOT = 0)


You can do the check!!
