Let's do 51 and 52.
51. The contrapositive has the same truth value as the original statement. That's opposed to the converse, which may or may not be true independent of the original statement.
The contrapositive of IF P THEN Q is IF not Q THEN not P. They're equivalent. Here that's If the cat is not female then it is not tricolor.
Answer: C
52.


For the statement to be true, the exponent must be zero:



Both positive 2 and negative 2 have a square of 4.
Answer: K
By the way, usually we assume
so the restriction that
isn't really necessary. Think of the definition of a polynomial or the binomial expansion:


For these common equalities to work when
we need to define 
Answer:
- <u><em>31 animals</em></u>
Explanation:
The question is in French language. The translation to English is:
<em>1 rabbit saw 6 elephants while going to the river. Each elephant saw 2 monkeys go towards the river. Each monkey holds 1 parrot in its hands.</em>
<em>How many animals are going to the river?</em>
<em />
<h2>Solution</h2>
<em />
Animal amount
Rabbit 1
Elephants 6 (the rabbit saw 6 elephants)
Monkeys: 6 × 2 = 12 (2 monkeys per elephant)
Parrots: 12 × 1 = 12 (1 parrot per monkey)
=============================
Total: 1 + 6 + 12 + 12 = 31 animals ← answer
