Answer:
4 or 7 (Check the explanation to see which one your equation actually is.
Step-by-step explanation:
One thing I want to clarify for you, It's Evaluate, not Avaluate.
Okay so, we want to find the value of 2^3x-1 and we know x = 1.
You didn't really clarify if the expression was [tex]2^{3x-1}[/tex] or [tex]2^{3x}-1[/tex], so I'll be doing both:
For [tex]2^{3x-1}[/tex], we should plug in x to get [tex]2^{3(1)-1}[/tex] and then simplify to get [tex]2^{2}[/tex].
2 to the power of 2 or [tex]2^{2}[/tex] is equal to 2 * 2 or 4.
The second one, [tex]2^{3x}-1[/tex], we should plug in x to get [tex]2^{3(1)}-1[/tex] and then to become [tex]2^{3}-1[/tex]. 2 to the power of 3 or [tex]2^{3}[/tex] is 8 and then minus 1 is 7.
