The first statement comes about because
a could be (say) 5
b could be (say) 6
Then c would be square root of 25 + 36 = 61 which is irrational.
I'm not sure of the wording of the second one. It reads like (5 + 6)^2 = 121 the two rationals added together make a rational number in my example. So I think that part is wrong. the second part is correct. For example sqrt(5) + sqrt(6) doesn't produce anything that is rational.
It doesn't have to. pi^2 + [cube root(10)]^2 does not produce anything rational and that is certainly not a perfect square. My first example shows that as well
I think the last one might be true.
Answer:
Well it will be 7+5=12 and 6+6=12
Step-by-step explanation:
The left side is IRRATIONAL. This is because the square root of 2 cannot be represented in terms of a ratio (or fraction).
Answer: The answer might be 2x^10-91. (I'm not sure tho)
