You can use this equation to help you: (ab)^2 = a^2 b^2. And also (a^m)^n = a^m*n

So, here it is:

(7ab^3)^2 = 7^2 a^2 b^3*2 = 49a^2b^6

The correct answer is the third one - 49 a^2 b^6.

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:

46.5

Step-by-step explanation:

A=a+b/2*h

A=12.7+5.9/2*5

12.7+5.9=18.6

18.6/2=9.3
