Question

2log-a^x + log-a^2 =log-a (5x + 3) solve for x?

Answer 1

it's # 5

Answer 2

Sorry idk :(

Answer 3

Use a calculator the Log function. I forgot how to do this

Answer 4

aw it's ok.

Answer 5

so log_a what mean ? logarithm base how many ?

Answer 6

i'm not sure

Answer 7

so on the attached page i see it clearly

there is log base a

Answer 8

so what you have wrote above here is the 59 exercise

yes ?

Answer 9

I didn't write any of it, my teacher did. :/

Answer 10

ok

do you know the property of logarithms ?

Answer 11

for example log a + log b = ?

Answer 12

I'm not so sure? you mean like when you add them log a + log B = log AB and that stuff?

Answer 13

yes you are right

Answer 14

and do you know how will be

log x^2 = ?

Answer 15

this log mean always base 2

Answer 16

which one are you looking at? I'm looking at #6 and I think the base is 5.

Answer 17

oh whoops wait

Answer 18

no you're right I was looking at the wrong one

Answer 19

ok so the base is 2, awesome

Answer 20

check the 5 nr.

Answer 21

with that knowledge, should I go ahead and add them together?

Answer 22

but how do I know the base is 2? ahhh I'm so sorry I'm so confused.

Answer 23

ok just a moment

from these 3 what you need to solve it ?

Answer 24

x

Answer 25

and in the last one, t.

Answer 26

she gave us the answers so that we can know if we did it correctly but I still have to do the work.

Answer 27

can you rewriting it here now ?

Answer 28

2loga x = ?

Answer 29

this 2 what mean ?

Answer 30

ohh it's the exponent.

Answer 31

a squared

Answer 32

not sure is the exponent of x because a is the base of logarithm

Answer 33

Well that's what I think... That's just how she wrote it.

Answer 34

ok

so than can you rewriting this exercise what you like we solve it together and and the second will solve it you

ok ?

Answer 35

ok sounds good.

Answer 36

what you wann we solving here together ?

Answer 37

so 2loga^x + loga^2 = loga(5x+3)

Answer 38

sure. Like that?

Answer 39

ATTENTION never not will be right using the sign of exponent how you have wrote above because this mean ,different thing here

what you have wrote there mean 2 time logarithm base 2 of a on exponent x

Answer 40

you can writing logarithm base a of x like log_a x

Answer 41

rewrit it please so

Answer 42

ok so 2loga_x + loga_2 = loga (5x+3)

Answer 43

the _ sign you need writing next a

so log_a x

ok ?

Answer 44

hence

2log_a x +log_a 2 = log_a (5x+3)

so than now on the left part what you can doing ?

Answer 45

you can combine the two logs.

Answer 46

yes how ?

Answer 47

you add them. so would it be log_a x2 = log_a(5x+3)? I'm just guessing.

Answer 48

ok but where is the 2 from the 2log_a x ?

Answer 49

I'm not sure. All I can think to do is put it with the x.

Answer 50

you have wrote it above that the 2 from 2log_a x what mean ?

Answer 51

check it please above on your first answers

Answer 52

I'm sorry I have to go, I think I'll just ask my teacher tomorrow. But thank you for your time!

Answer 53

2log_a x = log_a x^2

yes ?

Answer 54

than there will be

log_a x^2 + log_a 2 = log_a 2x^2

ok ?
