Cho $\log _{a} b=2$ và $\log _{a} c=3$. Tính $P=\log _{a}\left(b^{2} c^{3}\right)$

A. $P=13$ B. $P=31$ C. $P=30$ D. $P=108$ Ta có: $\log _{a}\left(b^{2} c^{3}\right)=2 \log _{a} b+3 \log _{a} c=2.2+3.3=13$.

Question

Accepted Answer

A.

$P=13$

B.

$P=31$

C.

$P=30$

D.

$P=108$

Ta có: $\log _{a}\left(b^{2} c^{3}\right)=2 \log _{a} b+3 \log _{a} c=2.2+3.3=13$.
