Question

Let....

Answer 1

A. 27

B. 7

C. 18

D. 13.5

Answer 2

log[ (A^3C^4)/(D^2) ]

log(A^3C^4) - log(D^2)

log(A^3) + log(C^4) - log(D^2)

3log(A) + 4log(C) - 2log(D)

Do you see what to do next?

Answer 3

hmmm do i substitute the values of A,B,C into those logs?

Answer 4

no

Answer 5

log(A) = 3

so you replace log(A) with 3

Answer 6

so 3(3) ?

Answer 7

yep that's part of it

Answer 8

kk so 3(3)+4(2)-2(5)
=9+8-10
=17-10
=7

so my answer is B. 7 ? :)

Answer 9

yep

Answer 10
