Question

i have log (base x+5) 0.0001= -3 i got x=15 is this correct?

Answer 1

\[\log_{x+5}(.0001)=-3 \]

Answer 2

is this how it is written?

Answer 3

yes :)

Answer 4

ok

Answer 5

ke (x+5) to the right side

Answer 6

in that case..
(x+5)^-3 = 0.001

Answer 7

isnt it?

Answer 8

x+5 = 10

Answer 9

x=5

Answer 10

0.0001 = (x+5)^-3
\[\sqrt[-3]{0.0001} = x+5\]

Answer 11

so it would be x=5?

Answer 12

yes

Answer 13

understand it>

Answer 14

yes in detail better :)

Answer 15

u want more detail?

Answer 16

what?

Answer 17

Answer 18

i mean to say \[\sqrt[-3]{0.0001}\neq 1\]

Answer 19

its a typo its actually 0.001

Answer 20

ok

Answer 21

it is a typo sorry!

Answer 22

\[\sqrt[-3]{0.001} = -0.1\]

Answer 23

=10

Answer 24

but x=5 was a choice is that not correct his math seemed correct.

there is not x=10

Answer 26

x+5=10 so x=5

Answer 27
