Question

solve question 5 with steps.

Answer 1

Hey there!

Given ,

a, b, c are positive real numbers .

We will use the formula :

$\frac{1}{ log_{a}(b) } = log_{b}(a)$

The equation reduces to

$\frac{ log_(ab) + log(bc) + log(ca) }{ log(abc) } \\ \\ = \frac{ log( {abc}^{2} ) }{ log(abc) } \\ \\ = 2 \frac{ log(abc) }{ log(abc) } \\ \\ = 2$

Refer the pictures for full solution

correct answer is Option C, 2

Hope helped! :)

Answer 2

= > log a + log b + log c = log abc.

The final answer is Option (C) - 2.

Hope this helps!
