Question

Plaese solve exponential equation: 4 over 9 exponent of C+3 = 3 over 2 exponent of C+9

Answer 1

How about writing that in a mathematical notation?

Answer 2

\[\left(\begin{matrix}4 \over\ 9\end{matrix}\right)^C+^3 = \left(\begin{matrix}3 \over\ 2\end{matrix}\right)^C+^9\]

Answer 3

c = -5

Answer 4

WHAT!! How did u get that??

Answer 5

Can you explain please.

Answer 6

Do you know logs?

Answer 7

yes

Answer 8

That's aweome.

\[\log(4/9)^{C+3} = \log(3/2)^{C+9}\]

Answer 9

Then,

\[(C+3) \log(4/9) = (C+9) \log (3/2)\]

Answer 10

Then,

\[(C+3)/(C+9) = \log(3/2) / \log(4/9)\]

Answer 11

That would make it equal -7

Answer 12

\[(C+3)/(C+9)=-0.5\]

Answer 13

oh k i got it thank you.

Answer 14

Cool, solve for C.
