Find the value of the expression below.
log5 2 + log5 10 - log5 4

A.   1

Step-by-step explanation:

To find the value of the expression, we will follow the steps below:

log₅2 + log₅10 -log₅4

From the rules of logarithm

logₐb + logₐc = logₐbc

similarly

logₐb - logₐc = logₐb/c

applying the two rules above to our expression will yield:

log₅2 + log₅10 -log₅4

=log₅(2 x 10) /4

=log₅20/4

=log₅5

also according to the rule of logarithm, logₐa=1

Therefore,

log₅5 =1

Therefore, the correct answer is 1

42.4
