Find X
27^4x2=243^3x=6
Please Explain
Thanks
Is this a repeat of the problem you posted earlier? If so, it should be
27^{4x2} = 243^{3x+6}
You might try it the hard way.
(4x2)*log 27 = (3x+6)*log (243)
Solve for x. I get 12. Post your work if you get stuck.
You have too many = signs. Is the second one (before the 6) supposed to be a + or  ? Is the first exponent supposed to be x2 or x ?
You need to learn how to use parentheses to clarify your equations when typing them.
