Find the exact solution to the equation. Show your work for credit. (1 point) four to the power of quantity twelve minus four x
equals two hundred and fifty six.
1 answer:
4^(12-4x)=256 realize that 256 is 4^4 so we really have:
4^(12-4x)=4^4 taking the natural log of both sides
(12-4x)ln4=4ln4 dividing both sides by ln4
12-4x=4 subtract 12 from both sides
-4x=-8 divide both sides by -4
x=2
