Answer:
The would -4 to the exponent of 3
4^3
Step-by-step explanation:
X+27=4x+12
X+15=4x
15=3x
5=x
Write both sides as powers of 8, then simplify:
However, on the left hand side, this would mean we'd have, , which is undefined (assuming the real-valued logarithm), so this equation has no real solution.
