Question

if log7 x= 1, then X=7.​

Answer 1

Step-by-step explanation:

if log7 x= 1, then X=7.

log7x=1

x=7¹

x=7

hence proved..

Answer 2

Answer:

$if \: x \: = {b}^{y} \: then \: log_{b} \: (x) = y$

$b \: log(x) \: {b}^{y} \: = x$

$log_{7} \: x = - 1$

$7 log {7}^{x} \: = - 1$

$x = 7 - 1 = \frac{1}{7}$
