Answer 13

umm 5?

Answer 14

right

Answer 15

are you getting the idea?

Answer 16

kinnda lol i think what would \[\log _{3} 18 \] bee cuz i cant get it

Answer 17

here 2 ^x = 18 where x = required log
now this cant solved by inspection as the other 2 could
so you preceed as follows:


ln 2^x = ln 18 where ln is natural log or log to base e
by laws of logs

x ln 2 = ln 18
x = ln 18 / ln 2
which you can do with your calculator

Answer 18

its 3 tho

Answer 19

oh - r us sure its log2 18 not log2 8?

Answer 20

because 2^3 = 8

Answer 21

nope log3 18

Answer 22

log to base 3 of 18

Answer 23

k

Answer 24

gotta go katie
