Question

how do you write this logarithmic expression as a single logarithm : 5 log 3 + log 4

Answer 1

log 3^5 + log 4 = log (243*4)

Answer 2

does t make sense?

log (a * b) = log a + log b
and n log x= log x^n

Answer 3

yea it does make sense , thank you

Answer 4

:)

Answer 5

bt are u sure it is right?

Answer 6

because isnt it supossed to be like similar to this problem : log 7 + log 2 which equals log 3.5 because u have to divide 7/ 2 .... right ?

Answer 7

@akash123

Answer 8

log (a * b) = log a + log b
so log 7 + log 2 = log (7 * 2)= log 14

Answer 9

log 7 - log 2 = log(7/2) = log 3.5
since log a - log b = log(a/b)

Answer 10

wait i dont get it ... why did u just change ur answer from multiplying to dividing the problem ?

Answer 11

log ( a *b)= log a+ log b
log(a/b) = log a - logb

Answer 12

in the beginning, it was a typo but i changed it at that time only

Answer 13

sorry...now it's fine?

Answer 14

5 log 3 + log 4= log 3^5 + log 4 = log (243*4)

Answer 15

wait i still dont get it so u multiply that problem instead of dividing ?

Answer 16

arent u supposed to divide?

Answer 17

@akash123

Answer 18

no...log a + log b = log (a*b)

Answer 19

oh okay thank you , bt why did u put 3^5 instead of putting 5^3

Answer 20

?

Answer 21

since n log x= log (x^n)
so 5 log 3= log (3^5) = log 243

Answer 22

oh okay thank you

Answer 23

so how do u solve log 8 - 2 log 6 + log 3

Answer 24

?

Answer 25

log 8 + log 3 - 2 log 6 = log( 8*3) - log (6^2) = log 24 - log 36 = log(24/36)

Answer 26

okay i have a couple more questions : how would you write these logarithmic expressions as a single logarithm :
1. 4 log m - log n
2. log 5 - k log 2
3.) log [ base of 6] 5 + log [ base of 6 ] x
4. log { base of 7 ] x + log [base of 7] y - log [base of 7] z

Answer 27

try 1st Q by ur own ...i'll help u

Answer 28

okay would the answer for the first one be .... log 4^m + log n = log 4/mn

Answer 29

4 log m = log m^4...right?

Answer 30

ye i think so

Answer 31

4 log m - log n = log m^4/n

Answer 32

oh okay i get it

Answer 33

so what is the answer for the ne

Answer 34
