B.log4 3 + log5 3
C.log9 3 + log9 3
D.log3 9 + log3 9

Answer 1

log9 4 + log9 5

is it supposed to be
\(\huge log9^4 + log9^5\ \ ?\)

Answer 2

YES @jdoe0001

take a peek at the Product rule

Answer 4

shoot, not that one hehe

Answer 5

the POWER rule rather

Answer 6

well, both really :)

Answer 7

OKAY I SAW THE RULE

Answer 8

and those 2 rules is all you need for all those

Answer 9

NO I DONT HAVE TO SOLE ALL OF THOSE THERE THE ANSWERS IM SUPPOSE TO BE EVALUATION LOG9 9 @jdoe0001

Answer 10

ohh, ok then you only need the product rule

Answer 11

IM KIND OF CONFUSED ON HOW IM SUPPOSE TO DO THIS ?

Answer 12

@jdoe0001

Answer 13

$$
log\color{blue}{9^4} + log\color{green}{9^5}\\
log_b(\color{blue}{n}) + log_b(\color{blue}{\color{green}{m}}) = log_b(\color{blue}{n}\times \color{green}{m})
$$

Answer 14

I GOT D TO BE MY ANSWER @jdoe0001

Answer 15

well, you may wan to check your exponent rules too

Answer 16

see the 1st one, in yellow?

Answer 17

hmmm, wait ... lemme recheck ... myself

Answer 18

YES @jdoe0001

Answer 19

so,.... yeah, the 1st in yellow

Answer 20

I GT MY ANSWERTO BE (D) @jdoe0001

Answer 21

D: is
$$
log3^9 + log3^9 \implies log3^{9+9} \implies log3^{18}
$$

Answer 22

IT'S C @jdoe0001

Answer 23

C: wouild be
$$
log9^3 + log9^3 \implies log9^{3+3}
$$

Answer 24

C DOESN'T HAVE ^2 IT HAS 9

Answer 25

hmm, doesn't show in your lines up there

Answer 26

C.log9 3 + log9 3

Answer 27

YYES @jdoe0001

Answer 28

but anyhow, that's the Product rule

Answer 29

C.log9 3 + log9 3 I assumed it to be \(log9^3 + log9^3 \implies log9^{3+3}\)
