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.

121/8 - 35/4
The LCM will be 8
( 121 - 70 )/8
51/8 or 6.375 inches
Therefore, the leftover piece will be 51/8 inches long
