<em><u>Answer:</u></em>
4 or 7 (Check the explanation to see which one your equation <em>actually</em> is.
<em><u>Step-by-step explanation:</u></em>
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 or
, so I'll be doing both:
For , we should plug in x to get
and then simplify to get
.
2 to the power of 2 or is equal to 2 * 2 or 4.
The second one, , we should plug in x to get
and then to become
. 2 to the power of 3 or
is 8 and then minus 1 is 7.
