Find the value of $x$ from the following equation : $l o g_{x} 4 + l o g_{x} 16 + l o g_{x} 64 = 12$

Open in App

Solution

$l o g_{x} 4 + l o g_{x} 16 + l o g_{x} 64 = 12$
$l o g_{x} 64 \times 64 = 12$
$l o g_{x} 2^{12} = 12$
$12 l o g_{x} 2 = 12$
So, $x = 2$ .

Find the values of x in each of the following:

$(i) \frac{l o g 144}{l o g 12} = l o g x$

$(i i) \frac{l o g 125}{l o g 25} = x$

$(i i i) l o g_{x} 4 + l o g_{x} 16 + l o g_{x} 64 = 12$

{log}_{6} 54 + {log}_{x} 16 = {log}_{\sqrt{2}} x - {log}_{36} (4 / 9)

1 + {log}_{x} (\frac{4 - x}{10}) = ({log}_{10} {log}_{10} n - 1) {log}_{x} 10

n \in (1, 10^{4}) - {10^{3}}
