Answer:
x=0
Step-by-step explanation:
4 ( 2.5) ^x = 4
Divide each side by 4
4/4 ( 2.5) ^x = 4/4
( 2.5) ^x = 1
Take the log of each side
log ( 2.5) ^x = log (1)
x log ( 2.5) = log 1
x log (2.5) = 0
Divide each side by log (2.5)
x = 0

I think it is the first one: Different bar widths.
<u><em>x=-31.5 or x=-32.0 is the right answer. </em></u> First you had to multiply by -1.5 from both sides of equation. And it gave us, . And finally simplify, and it gave us the answer is x=-31.5. You can also round up to the nearest tenths is x=-32.0. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
