Question

Write the expression as a single logarithm.
log_3 40 – log_3 10

Answer 1

log340 – log310=log(340/310)

Answer 2

i think it is
\[\log_3(40)-\log_3(10)=\log_3(\frac{40}{10})=\log_3(4)\]

Answer 3

oh... i read it wrong, sorry

Answer 4

It goes off of the adding and subtracting logs. Just remember that if it says log(some value) - log (some other value). Then you divide the two values . If it is addition then put them together under the log and multiply. REmember: cannot do this if log bases are not the same

Answer 5

By under the log i mean.
Log (some value•the other value)
