I believe the correct answer is sentences 2,5 and 6.
Complex sentences are composed of one independent
clause and at least one dependent clause. The examples from "The Enigma
Machine” which are complex sentences are:
<span>2. </span>For
example, Bletchley Park was crucial in the Battle of the Atlantic, which lasted
six years.
5. This
was provided in a codebook, which was a monthly list of daily keys distributed
to various networks in the German military.
6. Since
the Enigma machine could encrypt text into over 150 trillion possible
combinations, Germans were convinced the codes were not decipherable.
<span>The
answer is no.
Let’s show how:
=> 32 is the product, now we need to find a negative item to be used as based
and exponent
=> -5 ^ 3 = -125 (not the answer)
=> -4 ^ 3 = -64 (not the number)
=> -3 ^ 3 = -27 (not the answer)
=> -2 ^ 5 = -32 (the answer is 32 but this is not a positive number but a
negative one , thus the answer is still NO.)</span>
