Take logs of both sides:-
ln 625^x = ln 5
x * ln 0.625 = ln 5
x = ln 5 / ln 625
x = 0.25 answer
No, you should have reduced each base to...
3^(3*2x) = 3^(2*(x-3))
and then you can cancel each base
3*2x = 2*(x-3)
6x = 2x-6
4x= -6
x = -3/2
The answer to this question is y = 13
So I assume you are trying to find the equation of the line.
So you are gonna use this equation:
y=mx+b
So the x and y are your x and y coordinate pair and the m is the slope. So now you just substitute and solve for b:
4=8(7)+b
4=56+b
subtract 56 on both sides
-52=b
so now lets plug this into the equation of the line:
y=8x+(-52)
hope this helps!
