Question

if 3 log (x+3) = log 27 then value of x ?

Answer 1

Hello :)

3log(x+3) = log27

Using property of log..

=> log(x+3)³ = log27

Now comparing numerical values.

=> (x+3)³ = 27

=> (x+3) = 3

=> x = 0....

Answer.........

Answer 2

Given:

3 log (x+3) = log 27

To find:

The value of x

Solution:

The required value is 0.

We can obtain the value by using the following formula-

log $a^{b}$=b log a

We will solve the given equation using the formula.

On solving, we get

3 log (x+3)=log $3^{3}$

3 log (x+3)=3 log 3

log (x+3)= log 3

(x+3)=3

x=3-3

x=0

Therefore, the required value is 0.
