Question

condense the expression

1/2 log5 16-3log5 x+4log5 y

Answer 1

hmmm ? I don't understand the equation.

Answer 2

\[1/2 \log_{5} 16- 3\log_{5} x+ 4\log_{5} y\]

Answer 3

do you know all the log rules?

Answer 4

if not - consult this page: http://www.purplemath.com/modules/logrules.htm
you should then be able to solve this

Answer 5

yes i think i do

Answer 6

an example step would be:\[3\log_5x=\log_5x^3\]

Answer 7

\[\frac 12 \log_5 16-3 \log_5 x+4 \log_5 y = \log_5 \frac{4 y^4}{x^3}\]

Answer 8

I guess FoolForMath has given away the answer - but try and do it yourself to convince yourself that this is the right answer :)

Answer 9

Yes I guess I am wrong.
