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,

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

netineya [11]

Answer:

x - 5

Step-by-step explanation:

$((x - 5) {}^{ \frac{3}{2} } ) {}^{ \frac{2}{3} }$

$(x - 5) {}^{ \frac{3}{2} } { \times }^{ \frac{2}{3} }$

$(x - 5) {}^{ \frac{6}{6} }$

$(x - 5) {}^{1}$

Therefore x - 5
