Answer:the answer is A
Step-by-step explanation:i just took the test
Jump at 5 means that your paying attention
<span> (8^ -2)(4^4)(16^ -1)
</span>
<span>a^-x=(1/a^x)
</span>
<span> (4^4)/((8^2)(16))
"NOTE" </span><span>16^1=16
</span>
<span>4^4=256
8^2=64
256/((64)(16))=1/4
</span>
<span>convert 1/4 to a power of two
</span>
<span>(4) is 2
1/4=1/(2^2)
</span>
<span>1^2=1
(1/2)^2=(1/4)
</span>
<span>1/2 to the power of 2 is the answer
It would look like this
1/2²</span>
Full question plzz we need to know what the core is
Since the string has already two 2, then we will compute the whole number of strings whose length is 4, over the alphabet {0,1}:

There is then 16 such strings.
