Use the power property to rewrite log3x9.

Kitty [74]

Answer:

$\log _3\left(x^9\right)=9\log _3\left(x\right)$

Step-by-step explanation:

Given the expression

$\log _3\:x^9$

now rewriting the expression

$\log _3\:x^9$

$\mathrm{Apply\:log\:rule\:}\log _a\left(x^b\right)=b\cdot \log _a\left(x\right),\:\quad \mathrm{\:assuming\:}x\:\ge \:0$

$=9\log _3\left(x\right)$

Therefore,

$\log _3\left(x^9\right)=9\log _3\left(x\right)$

Answer:

a > 12

Step-by-step explanation:

Best of Luck!
