Question

How do you convert numbers between bases?

Answer 1

what do you mean?

Answer 2

like how do you convert 345(base 10) to base 4?

Answer 3

\(\bf 345\times 10\implies \square \times 10^4\quad ?\)

Answer 4

base 10 like 345 with 10 small slightly below it

Answer 5

like this

Answer 6

\(\Large 345_{10}\qquad 345_{4}\quad ?\)

Answer 7

hmmm I guess... I dunno that notation

Answer 8

idk im new to bases

Answer 9

@phi @mary.rojas @MathLegend help me please

Answer 10

convert into logs with a common base
example log base 2 of 6 = log base 10 of 6/ log base 10 of 2

Answer 11

not that stuff or logs *facepalm

Answer 12

omg

Answer 13

log base 10 of 345 / log base 10 of 4

2.53/0.672 = 4.215

Answer 14

no no no
i mean log like this log

Answer 15

my calculator is not clear but the method is fine

Answer 16

the log like u multiply 2 by 1, add to (8*2), and add that to (4*2*2)
THAT KIND OF BASES

Answer 17

Read that for the base-change formula.

Answer 18

ok let me see

Answer 19

do you mean like counting in different bases for example we normally use 10 decimal but binary is base 2 ex 111 in binary to base 10 = 7

Answer 20

always use the base 10 to change from one base to the other if the bases are not multiples of each other

Answer 21

im not talking about log bases. im talking about number bases. like base 10, base 2, base 12,
like base 12 would have 0,1,2,3,4,5,6,7,8,9,A, and B

Answer 22

for example
45 base6 = 30 base10 = 11110 base2

Answer 23

always use base 10 as the jumping base. Got it?

Answer 24

45 base6 is actually 29base10.
i dont understand.
can u post a link to one of those chat rooms where multiple people can draw there?

Answer 25

sorry it should be 29 base10 and 11101 base 2

Answer 26

yeah

Answer 27

my calculations are really bad

Answer 28

lol can u post a link where we both draw?

Answer 29

You know how to do it. so why you want to post a link?

Answer 30

i dont know how to convert

Answer 31

but you just converted 45 base6 to base10

Answer 32

and converting something from base10 to another is the same

Answer 33

what I normally do is, use base10 as the linking bridge two the other bases all the time.

from the starting base to base10 and then from base10 to the final base
