Arjun incorrectly writes log7 + log7 − log7 as a single logarithm.

log7 + log7 − log7 = log7 ( + − )

Where did Arjun make errors? Explain his errors and the properties of logarithms that leads to the correct answer. State the correct answer.

I struggle in math and I've been trying this for an hour and I still can't get it

log7 + log7 − log7 = + log7

This is correct answer

Step-by-step explanation:

Explanation:-

we will use properties of logarithm

first property

i) log (ab) = log a + log b

second property  

ii)

Third property

iii)

Now given log7 +log7 - log7

                                           = log(7X7) - log7 ( used first property)

                                           = log(49)- log(7)

                                           =        (used second property)

                                          = + log(7)
