Question

is this statement true?
2 log 5 x + 1/2 log 5 y - 4 log 5 z = log 5 x^2√(y)/z^4

Answer 1

\[\Large 2\log_5(x)+\frac12 \log_5(y)-4\log_5(z)=\log_5\left(\frac{x^2\sqrt y}{z^4}\right)\]
is this what you mean?

Answer 2

no its y-4 but rest is right

Answer 3

not 4log

Answer 4

\[\Large 2\log_5(x)+\frac12 \log_5(y-4)-\log_5(z)=\log_5\left(\frac{x^2\sqrt y}{z^4}\right)\]

this?

Answer 5

yeah but no negative in front of log5 after the (y-4)

Answer 6

after (y-4) log... between log and y-4 what sign is there? multiply, plus, minus ?

Answer 7

is it plus?
