Question

Fill in the value of x.
log^81(1/9)=x

Answer 1

is it \(\huge \log_{81}(1/9)=x ??\)

Answer 2

then u just need 2 properties of log
\(\large log_ab=\frac{log b}{log a}\\ \large log a^n=nloga\)

Answer 3

i think i fpund new properties \[\log_{a^b }(c) = \frac{1}{b}\log_{a}(c) \] @hartnn can you verify

Answer 4

that is correct !
good work :)

Answer 5

could u solve further @smourin ?
