see where they have the same x and y values
that is at x=-1 and y=-5
intersect at (-1,-5)

Answer:
x ≈ 0.7798
Step-by-step explanation:
For this to be an exponential function, the variable needs to be in the exponent. That is, parentheses are needed.
e^(8x) = 512
8x = ln(512) . . . . . take the natural log
x = ln(512)/8 ≈ 0.7798
Answer:
7.8*10^7
1.0 * 10^4
Now divide 7.8/1.0 and the power goes up to be subtracted
=7.8 * 10^(7-4)
= 7.8 * 10^3
