Question

Solve 4^(x + 7) = 6^(x – 1)

Answer 1

You need to take the log of both sides, then you will have a linear equation in x which you can solve.

Answer 2

For example on the left hand side ...\[\ln(4^{x+7}) = (x+7) \ln4\]

Answer 3

Got it?

Answer 4

so i need to switch the log to different sides?

Answer 5

a different*

Answer 6

side*

Answer 7

No, just take the log of both sides and you see that you get terms like ln 4 and ln 6, which are just numbers.
