Question

12^x=46^x+3

Answer 1

What about it?

Answer 2

It's only numerically solvable for x, if that's the problem, and even in that case the two solutions are imaginary...

Answer 3

I need to find x

Answer 4

Are you sure you didn't copy it wrong? It's not algebraically solvable...

Answer 5

im sorry it is just 4 not 46

Answer 6

\[12^x = 46^{x+3}\]
maybe it's writtent hat way

Answer 7

\[12^x = 4^{x+3}?\]

Answer 9

Thanks, @mathg8 , that really helps...

Answer 10

i am willing to be that \(x+3\) is the exponent

Answer 11

how do you make it like that ^ this means the same thing you wrote doesn't it

Answer 12

Use latex

Answer 13

\[12^x=4^{x+3}\] like that one right?

Answer 14

i'd like it to be x+3 to be the exponent because im a sissy :D

Answer 15

I see ...typo

Answer 16

latex? and its a 4 not 46 yes satelite73 like that

Answer 17

haha okay you really have to be clearer. Maybe with parenthesis.

Answer 18

if you want to see the code, right click on the expression and select "show math as" then "latex"

Answer 19

latex is text-formatting-code-speak for fancy mathy stuff on the internet.

Answer 20

oooo thanks for the tip im sorry didn't mean to confuse any one... i am stressing out my homework is due by midnight and i do not understand ANY of it

Answer 21

ok here is what you do
write
\[12^x=3^x\times 4^x\] and
\[4^{x+3}=4^3\times 4^x\]

Answer 22

or, not using latex, use parentheses:
12^x= 4^(x+3)

Answer 23

cancel a \(4^x\) from both sides, since it is never zero and solve
\[3^x=4^3\] i.e. \(3^x=64\)

Answer 24

you good from there?
