Question

(A) Given,$a^x = b^y = c^z = d^w = k$ (let).Taking log with base $a$:$x = y \log_a b = z \log_a c = w \log_a d$.Thus,$\frac{1}{y} = \frac{\log_a b}{x}

$\log_a(bcd)$

(A) Given,$a^x = b^y = c^z = d^w = k$ (let).Taking log with base $a$:$x = y \log_a b = z \log_a c = w \log_a d$.Thus,$\frac{1}{y} = \frac{\log_a b}{x}$,$\frac{1}{z} = \frac{\log_a c}{x}$,and $\frac{1}{w} = \frac{\log_a d}{x}$.Now,$x\left(\frac{1}{y} + \frac{1}{z} + \frac{1}{w}\right) = x\left(\frac{\log_a b}{x} + \frac{\log_a c}{x} + \frac{\log_a d}{x}\right)$.$= x \cdot \frac{1}{x} (\log_a b + \log_a c + \log_a d)$.$= \log_a(bcd)$.

If $a^x = b^y = c^z = d^w$,the value of $x\left(\frac{1}{y} + \frac{1}{z} + \frac{1}{w}\right)$ is
