hi .
if we know that $\vec{A}.\vec{B_1} = \vec{A}.\vec{B_2}$ can we infer from that : $\vec{B_1} = \vec{B_2}$ ?

May 21, 2016
${\log}_{16} 512 = \frac{9}{4}$
#### Explanation:
The change of base formula tells us that if $a , b , c > 0$ then:
${\log}_{a} b = \frac{{\log}_{c} b}{{\log}_{c} a}$
Note that
$16 = {2}^{4}$
$512 = {2}^{9}$
