Question

PLEASE HELP!!
Which of the following is the solution of log base x + 5 0.001 = –3 ?
x = 5

x = 7

x = 13

x = 15

Answer 1

\[\log _{x+5}0.001 = -3\]

Answer 2

means you have to solve \((x+5)^{-3}=0.001\)

Answer 3

and since \(10^{-3}=.001\) you know \(x+5=10\)

Answer 4

by laws of logarithms

if log base a of x = y
then a^y = x
- as satellite says

Answer 5

so x = 5

Answer 6

yes
