Log_c(A)=2<br> log_c(B)=5, <br> solve log_c(A^5B^3)

vlabodo [156]

We know that $\log_a(bc)=\log_a(b)+\log_a(c)$ .

Using this rule,

$\log_c(A^5B^3)=\log_c(A^5)+\log_c(B^3)$ .

We also know that $\log_c(a^b)=b\log_c(a)$ .

Using this rule,

$\log_c(A^5)+\log_c(B^3)=5\log_c(A)+3\log_c(B)$

Now we know that $\log_c(A)=2,\log_c(B)=5$ so,

$5\cdot2+3\cdot5=10+15=\boxed{25}$ .

Hope this helps :)

Answer:

A. AE, EC

Step-by-step explanation:

Because you know that the bottom two angles are congruent, you can conclude that this is an isosceles triangle. This means that the sides are congruent.
